Jakarta: Menyebut kata pertama "hiu" tentu saja nyali rasanya ciut. Namun di sinilah letak kesalahpahaman orang tentang salah satu ikan besar bernama Hiu Paus.

Memiliki nama latin Rhincodon typus atau yang dalam Bahasa Inggris disebut Whale Shark ini ternyata salah satu ikan yang ramah karena ikan ini adalah hiu pemakan plankton yang merupakan spesies ikan terbesar. 

Cucut ikan ini mendapatkan namanya whale shark karena ukuran tubuhnya yang besar dan kebiasaan makannya dengan menyaring air laut menyerupai kebanyakan jenis paus.

Dan untuk bisa menikmatinya tak perlu jauh-jauh ke luar negeri, karena di Indonesia Anda pun bisa melihat pesona keindahan ikan yang dipercaya dapat hidup hingga berusia 70 tahun ini.

Terletak tak jauh dari pusat kota Gorontalo, sekitar 40 menit saja Anda bisa menemukan salah satu tempat wisata yang mungkin jarang ditemukan di tempat lain yaitu bjek wisata Hiu Paus. 

Objek wisata tersebut tepatnya berada di Desa Botubarani, Kabupaten Bone Bolango, Gorontalo. Sebuah tiang yang bertuliskan Objek Wisata Hiu Paus menjadi penanda untuk memasuki kawasan tersebut. Di sini Anda bisa melihat hiu paus dan memberinya makan secara langsung.

Awal Mula Keberadaan Hiu Paus di Gorontalo

"Awal mula ada seperti ini sejak tahun 2016. Jadi dulunya ada pabrik pengolahan ikan dan kemudian limbahnya dibuang ke laut. Nahm ketika dibuang ke laut maka lautnya pun menjadi subur sehingga banyak plankton dan ikan-ikan kecil kemudian barulah banyak hiu paus yang datang ke sini," tutur Fahmi Isnan, Staff Dinas Pariwisata Gorontalo ketika ditemui tim Medcom.id.

Ia juga menambahkan bahkan pada tahun 2016 jumlah hiu paus yang datang ke perairan laut di Desa Botubarani pernah mencapai 14 ekor. "Bahkan pernah ada yang panjangnya mencapai 9 meter dan lebar mulutnya sampai 2 meter," katanya. 

Hiu yang mengembara di samudra tropis dan lautan yang beriklim hangat ini juga unik karena memiliki ukuran mulut yang sangat lebar yaitu sekitar 85 cm. Dengan panjang tiga sampai lima meter, atau bahkan tujuh meter tubuh mereka dipenuhi dengan bintik-bintik putih yang memang merupakan salah satu ciri khas hiu paus.

Kenal Lebih Dekat Hiu Paus

Di obyek wisata hiu paus ini disediakan alat untuk snorkeling dan diving bagi Anda pecinta air. Namun jika Anda tidak mau terkena air tetapi ingin melihat dan memberi makan hiu paus secara langsung, bisa memilih untuk menaiki perahu kayu yang juga tersedia di sana. Dengan membayar tiket masuk sebesar Rp25 ribu, Anda bisa langsung menyaksikan kemunculan hiu paus dengan jarak hanya 5-10 meter dari bibir pantai.

Bagi Anda yang ingin mencoba untuk snorkeling, bisa membayar alat snorkeling seharga 250 ribu sedangkan untuk menyewa peralatan diving lengkap cukup merogoh kocek sebesar Rp450 ribu.

Menurut Pak Rismo, salah seorang nelayan di area konservasi Hiu Paus Desa Botubarani, pengunjung obyek wisata hiu paus paling ramai pada bulan Juni dan saat liburan sekolah. Untuk obyek wisata hiu paus sendiri, sudah dibuka sejak pukul sembilan pagi sampai pukul setengah enam sore waktu setempat.

Namun Fahmi memberikan saran ketika berenang bersama hiu paus sebaiknya perlu mewaspadai ekornya karena berbahaya. Dan sebaiknya ketika mau berfoto dengan hiu paus tidak menggunakan blitz atau lampu kilat.

Stunning photos capture rare bioluminescent plankton caused by hot weather

Stunning photos have captured the outbreak of a rare and beautiful phenomenon caused by the recent hot weather.

The hottest summer we’ve had for decades has caused a surge in bioluminescent plankton, causing glowing seas around the British coast.

Tim Bow captured the fantastic sight at Aberavon Beach, Port Talbot, Wales.

‘It’s been spotted at different locations along the South Wales coast in the past week although it’s slightly unpredictable.

A photographer snapped these stunning images of the sea glowing blue as millions of plankton lit up like fireflies.

Photographer Tim Bow captured the rare natural phenomenon off the coast of Port Talbot, Wales, last week, amidst a spike in the sightings of bioluminescent plankton. 

Scientists believe the phenomenon is the result of plankton being disturbed, causing them to emit light though a complex chemical reaction.

Dazzling: The sea off Port Talbot, Wales, glows blue with the light of bioluminescent fireflies

Supernatural: The plankton emit a blue glow that creates eerie designs in the water

It is thought the recent surge in sightings of bioluminescent plankton has been caused by the heatwave.

Photographer Tim Bow snapped these breathtaking images on Friday night. 

He said: 'Bioluminescent plankton is randomly popping up at different locations around Wales.

Stunning: Residents admire the stunning cobalt blue glow of the plankton in Port Talbot

Bioluminescence is the production and emission of light by a living organism.

It occurs widely in marine vertebrates and invertebrates, as well as in some fungi and microorganisms such as phytoplankton.

What is bioluminescence?  

Bioluminescence is the production and emission of light by a living organism.

It occurs widely in marine vertebrates and invertebrates, as well as in some fungi and microorganisms such as phytoplankton.

The word comes from the Greek 'bios' for living and the Latin 'lumen' for light.

Bioluminescence is a type of light energy produced by a chemical reaction.

Different types of animals use bioluminescence in different ways.

Deep sea squid use it for counter illumination camouflage so they match their environmental light, but Anglefish use it to lure prey with a light-up dangling appendage from their head that draws in smaller fish, which they can eat.

Fireflies use bioluminescence to attract mates by flashing their abdomens, while their larvae use it to repel predators.

Millipedes also glow to put predators off of eating them.

Enough plankton, and you sir, have a whale

It has been a couple of weeks of belief and varying degrees of success.

From the rescue of the incredibly brave football team in those very dark caves in Thailand to England getting to a semi-final in the World Cup and an unlikely South African hero called Kevin Anderson, who with his dodgy knees beat Roger Federer, the greatest of all time, to make a Wimbledon Final.
Watching all these news stories, I noticed something a little strange. Take the cave story in Thailand. The reporters would ask the divers and dive experts massive questions. “Would the children in the cave live? How is this all going to end?” In other words, what would the outcome be? What will happen in the future?

The divers would always respond to the reporters’ big questions with small answers. “We just have to focus on replenishing the air bottles and continue to follow our plans.” In other words, we are just going to focus on right now.

Harry Kane was repeatedly asked if England would win the World Cup. “Is it coming home?” His answer was always about focusing on what they had to do right now. The small details they have to get right, right now. Their success was based on being granular. It helped them focus on what they could control and deal with the expectations of a nation.

A giant tomorrow

Kevin Anderson, in his post-match interview after beating Roger Federer in the Wimbledon quarter final, said that in the fourth set of their marathon-long five-set match, he started to think about winning. Of what might be. He admitted he had to quickly banish those thoughts and just focus on the next point. He had to focus on ‘right now’.

Success and the future is something everybody speaks about a lot. Doing and the present is always done by the very few. It would seem success in our minds is made of a giant tomorrow.

It is filled with massive ambition and massive results. However, in reality, success seems to happen when you focus on the smallest actions and get them right. And that happens when you’re able to focus on the present.

And that happens when you believe in your own ability or what you’re doing.

So, although belief in our business is slightly unfashionable these days, it would seem success of any kind is literally impossible without it.

Why belief is unfashionable

Belief has become unfashionable because way too many posters have been put up with snappy slogans on agency walls. This is just window dressing that doesn’t help anybody. It is the easy alternative to creating an agency where you believe you can do something special. And doing something special normally begins with being in a place that makes you believe you can. So, that is the first part.

The second part for creatives is about craft. It is about doing the small things that often don’t seem important, correctly. It is about focusing on right now, rather than on the outcome. Large belief meets tiny, seemingly unimportant actions, and bingo.

These days, the world is often about speed and output. We all just want the outcome rather than looking at the tiny unglamorous steps to get there. This week was a great reminder that if you want to do something properly, there are no shortcuts. You have to have the right ingredients. You have to have belief. You have to be prepared to graft.

A grandiose vision is the easy part. Everybody has them. In fact, these days, many mistake the vision for the finished article. It is a big mistake that makes a huge amount of work look the same. I wonder how long it will be before anybody notices?

The truth is, for a creative, creating Moby Dick often begins with the tedious, yet essential task, of finding enough plankton right now and having the slightly strange belief that a majestic whale will eventually occur.

However, the world always wants the whale to happen right now.

But whales don’t happen that way.

Inilah 5 Fakta Tersembunyi Chum Bucket, Restoran dan Markas dari Plankton dalam Mencuri Resep Krabby Patty

Dalam serial SpongeBob Squarepants, Krabby Patty dikenal sebagai makanan terlezat se-Bikini Bottom. Makanan ini hanya bisa ditemui di restoran milik Mr. Krabs, Krusty Krab. Saking enaknya rasa Krabby Patty, membuat Plankton yang notabene adalah musuh dari Mr Krab sangat iri. Bahkan ia terus berusaha mencuri resep makanan yang bentuknya mirip humberger tersebut.

Demi menyaingi kepopuleran Krusty Krab, Plankton pun membuka sebuah restoran yang diberi nama Chum Bucket. Nama restoran ini adalah plesetan “Chum bucket”, yang merupakan wadah dari materi hewani atau nabati, seperti kepala ikan dicincang dan jagung, biasanya dibuang di permukaan air untuk menarik ikan untuk ditangkap.

Nah apalagi fakta Chum Bucket yang belum banyak diketahui oleh penonton setia serial SpongeBob Squarepants?

Letak Chum Bucket

Sebagai dua restoran yang saling bersaing, Chum Bucket berdiri tepat di depan restoran Krusty Krab. Sayangnya, Krusty Krab jauh lebih populer dan sukses dibandingkan dengan Chum Bucket milik Plankton. Chum Bucket merupakan bagian dari “Sheldon Plankton Enterprises, sebuah divisi dari No Fun Incorporated.”

Gagalnya bisnis Chum Bucket bukan karena makanan enak yang terdapat di Krusty Krub, tapi juga hasil dari makanan yang mengerikan dan berpotensi beracun yang disajikan di restoran Chum Bucket.

Produk Makanan

Fakta Chum Bucket selanjutnya adalah tentang produk yang dihasilkan. Ya, meski dikenal sebagai restoran yang gak laku, tapi Chum Bucket banyak menghasilkan produk-produk makanan. Uniknya, semua produk makanan yang disajikan berawalan kata “Chum”.

Produk makanan pertama yang ditawarkan oleh Chum Bucket adalah Chum Burger. Produk ini diciptakan oleh Plankton saat berseteru dengan Mr. Krabs. Pelanggan pertama yang mencicipinya adalah teman sekelas Plankton, Johnny.

Selain Chum Burger, ada juga produk makanan lain seperti Chum Fries, Chum Shake, Chumstick, Chumbalaya, Chum Chilli, Chum Pie, dan Chum Joes.

Incredible Bioluminescent Sea Sparkles Cause a Glowing Shore in Wales

No, your eyes are not deceiving you. The glowing sea isn't the result of Photoshop, but some of nature's smallest organisms. Captured off the coast of North Wales by photographer Kris Williams, the phenomenon is caused by bioluminescent plankton. Though typically found in the warm waters of the Caribbean or Southeast Asia, the glow is a defense mechanism that Williams first spotted at Penmon Point beach on the island Anglesey a few weeks ago.

Bioluminescence is when living organisms produce and emit light. It's used by both marine and terrestrial vertebrates and invertebrates for a variety of purposes—camouflage, mimicry, communication, and defense. In the case of Noctiluca scintillans or sea sparkle, the glow is a defense for the plankton, who make their predators more vulnerable to larger predators due to the light. The bioluminescence is evident when the water is disturbed by waves—or photographers trying to get a good shot.

“I've been fortunate enough to witness the bioluminescence on the Welsh coast many times over the past five years, both in North and South Wales,” Williams shares. “You can scoop the water up in your hands and see the plankton covering your fingers like tiny stars, or swim in the water and watch as the waves light up where you swim through them. It really is something magical to see and experience!”

Aside from incredible still photographs—which are available for purchase by contacting the photographer—Williams also recorded live video of the natural phenomenon over the course of two nights. In the footage, it's amazing to see how the natural light show dances along the water.

There's something 'magical' in the water in Wales right now

It seems all over Wales people have been encountering beaches glowing with a mysterious other-worldly neon hue.

This strange phenomenon, captured in June by photographer Kris Williams (@jixxerkris) in the viral footage above, is reportedly caused by bio-luminescent plankton, which have been lighting up the coastline like nuclear waste when agitated — a mechanism used to ward off predators.

After being featured in Twitter's 'Moments' feed, Williams' breathtaking footage has been picked up by major news outlets all over the world, with many equally baffle and delighted that the phenomenon even existed in that part of the world.

In the night time clip, a dark figure can be seen trumping through pitch-black water along the coast of Anglesey in Northern Wales, with the beach remarkably lighting up like lightning bolts with each footstep.

Ripples of neon blue appear as the figure stomps through the inky waters. The most dramatic effect happens when the mystery figure throws debris into the ocean from the beach, causing an explosion of electric blue.

"Oh wow!!! I didn't know you could see this sort of thing in the UK. #Magical" writes one Twitter user.

Amazingly, while this phenomenon is rare, it's by no means the first time the glowing plankton has appeared in this part of the world.

"I saw this down the Gower a few years ago, it's amazing," one twitter user said, referring to the Gower Peninsula, a coastal region in South Wales.

The photographer has also had the great fortune of capturing the bio-luminescent waves and an aurora at the same time, as seen in this remarkable image dated at 2015, shared on the photographer's public Facebook page. It certainly has our wanderlust cylinders firing for a trip to the British Isles.

Memungut Sedotan Demi Kurangi 5 Triliun Sampah Plastik di Lautan

Sydney -

Sebuah proyek sains dari warga global yang diluncurkan di Sydney akan merekrut siswa dan relawan untuk menghitung dan mencatat beberapa dari lima triliun potongan plastik di lautan.

Proyek Pengamatan Mikroplastik Australia (AUSMAP) akan melatih para relawan untuk mengumpulkan mikro dan makro plastik dari garis pantai di seluruh Australia.

Direktur program ini, Dr Michelle Blewitt, mengatakan tujuannya adalah untuk mendapatkan data tentang jumlah plastik di lingkungan laut, di mana lokasinya dan dari mana asalnya.

"Ada sekitar lima triliun potongan plastik di lautan kita saat ini ... dan hanya ada tiga triliun pohon, jadi ada lebih banyak plastik di laut daripada pohon di planet kita.

"Plastik tak hanya menjerat hewan, hewan-pun menelan plastik ini. Plastik yang lebih kecil juga tertelan hewan sekecil zoo plankton, dasar dari rantai makanan."

Proyek, yang dirancang untuk melibatkan siswa dari kelas 9 hingga 12, ini akan menggunakan metode ilmiah yang ketat untuk mengumpulkan data dari garis pantai.

"Kami menggunakan dua metode: garis transek di mana mereka mengumpulkan barang-barang besar - botol plastik, kantong plastik, apa pun yang terlihat - [dan] data itu ditambahkan ke dalam database proyek Australian Marine Debris Initiative," kata Dr Blewitt.

"Kami juga mengumpulkan mikroplastik, yang berukuran satu hingga lima milimeter sehingga terlihat oleh mata telanjang."

"Kami mengumpulkan dua sentimeter teratas dari pasir di kuadrat dan kami menyaringnya melalui saringan berukuran berbeda. Yang tersisa adalah apa yang kami susun, dan kami periksa dan kami hitung serta kami ukur."

Menyusul peluncuran tersebut, AUSMAP akan bekerja untuk menciptakan pusat regional di mana peralatan akan tersedia bagi siapa saja untuk berpartisipasi.

"Tujuannya adalah untuk melibatkan warga ... karena kami merasa bahwa semakin banyak orang yang terlibat dengan sesuatu seperti ini, semakin mereka siap menjadi aktivis lingkungan untuk meminimalkan sampah plastik kita masuk ke lautan kita," kata Dr Blewitt.

Dr Blewitt mengatakan, mikroplastik tertelan oleh hewan seperti plankton. (ABC Sydney: Harriet Tatham)

Libatkan relawan lokal

Relawan penyelam dangkal, Harriet Spark, mengatakan, sementara air di lepas pantai Sydney bisa sedikit dingin selama musim dingin, hasilnya membuat upaya ini berharga.

"Saya seorang instruktur selam dan saya dulu bekerja di akuarium, yang sekarang ditutup," katanya.

"Seorang kolega dan saya sendiri dulunya snorkelling (menyelam dangkal) di sini dan kami menemukan begitu banyak sedotan, dan orang-orang begitu terkejut oleh mereka (sampah sedotan), jadi saya pikir bayangkan jika kami mengumpulkannya, kami bisa menunjukkan kepada orang-orang betapa besar dampak yang ditimbulkannya."

Terinspirasi untuk berbuat lebih banyak, Spark meluncurkan Operasi Sedotan yang mendorong para relawan untuk snorkeling ke Manly Cove dan mengumpulkan sampah plastik.

"Kami mengumpulkan sedotan setiap akhir pekan dan menghitung berapa banyak yang kami temukan dan menggunakan ini untuk mencoba dan membuat bisnis mengubah praktik mereka dalam penggunaan sedotan dan plastik lainnya," katanya.

"Selama musim panas 2017-18 kami menemukan lebih dari 2.500 sedotan."

"Itu membuat saya merasa sangat frustrasi dalam hal sedotan karena mereka adalah barang yang kecuali Anda memiliki kondisi medis tertentu, anda tidak benar-benar perlu menggunakannya."

Warga lokal Manly Cove mengatakan, sementara kesadaran seputar sedotan plastik berkembang, masih ada bisnis yang praktiknya ia harap ada perubahan.

"Kita semua bisa berkata tidak pada sedotan, tetapi jika sebuah bisnis mengatakan tidak pada sedotan, mereka memotong begitu banyak sedotan dari berakhir di tempat pembuangan akhir atau tempat sampah atau akhirnya lautan."

Selama periode musim panas 2017-2018, para penyelam dangkal mengumpulkan 2500 sedotan dari telukManlyCove. (Supplied:Operation Straw)

Ilmuwan Inggris Ciptakan Plastik yang Mudah Terurai

KOMPAS.com - Sampah plastik menjadi masalah di seluruh dunia. Pasalnya, sampah ini sulit terurai di alam.

Namun, kini, para peneliti dari University of Warwick, Inggris menciptakan plastik biodegradable yang bisa dibuang bersama sisa makanan. Plastik ini akan lebih mudah terurai di alam karena menggunakan bahan dasar alami.

Bahan penyusunnya adalah "lem pohon" yang disebut dengan lignin.

Lignin menyimpan serat selulosa bersama-sama yang membuat batang tanaman menjadi tegak dan kuat. Para peneliti kemudian membuat senyawa ini menjadi plastik yang kuat dan mudah dibentuk.

Sebagai informasi, lignin merupakan produk sampingan dari pembuatan kertas.

Meski membuat batang kayu menjadi tegak dan kuat, senyawa ini pada bubur kayu menjadi lemah dan berubah warna. Karenanya, senyawa ini dipisahkan pada pembuatan kertas.

Melihat "limbah" pembuatan kertas ini, Profesor Tim Bugg mengembangkan cara untuk memanfaatkannya.

Bugg dan koleganya mengunakan bakteri yang dimodifikasi secara genetik untuk mengubah lignin menjadi bahan kimia berguna.

Bakteri tersebut adalah Rhodococcus jostii yang hidup di tanah dan memakan lem. Bakteri ini diubah secara genetis untuk mengubah lignin menjadi hasil tinggi dari plastik biodegradable.

"Saya telah bekerja dengan lignin selama 40 tahun dan ketika saya memulai proyek ini, orang orang berkata 'Anda membuang waktu' tetapi sekarang mereka berpikir ini mungkin," ujar Profesor Bugg dalam sebuah acara di Central London dikutip dari The Telegraph, Rabu (04/07/2018).

"Masih sulit tapi itu mungkin," tegasnya.

Bugg menjelaskan bahwa hanya ada sedikit organisme yang bisa memecag lignin. Untuk itu, dia dan tim menggunakan materi genetik dari dua strain bakteri untuk mempercepat prosesnya.

"Biasanya bakteri menggunakannya untuk pertumbuhan, dan memecahnya menjadi molekul kecil yang digunakan sebagai makanan untuk tumbuh," ujarnya.

"Jadi kami mempercepat proses itu sehingga meski bakteri masih bisa berkembang tetapi bisa melakukan sesuatu untuk kami pada saat yang sama," sambungnya.

Proses percepatan ini dikarenakan lignin merupakan senyawa yang kompleks.

"Karena lignin itu kompleks, untuk itu dalam menguraikannya Anda akan mendapat campuran yang rumit. Namun, kabar baiknya adalah dengan bakteri ini mereka bisa melakukan semuanya. Kami berharap lima tahun lagi semua akan selesai," tambahnya.

Untuk diketahui, plastik sangat sulit didaur ulang. Hanya 12 persen sampah rumah tangga bisa melalui proses ini.

Sisanya dibakar atau dibuang ke tempat pembuangan sampah.

Padahal, setiap tahunnya, lebih dari 300 juta taon plastik diproduksi secara global. 10 persen di antaranya berakhir di lautan.

Bahkan, kini diperkirakan rasio plastik dan plankton adalah 1:2. Jika terus dibiarkan, jumlah plastik di lautan akan lebih banyak dibandingkan jumlah ikan pada 2050.

Lagi, Perempuan New York Alami Masalah Kuku Setelah Lakukan "Fish Spa"

KOMPAS.com - Fish spa atau terapi gigitan ikan, diyakini bisa menghilangkan sel kulit mati dan menghaluskan kulit.

Sejak terapi ini dikenal masyarakat, para ahli sebenarnya sudah memperingatkan adanya risiko penyebaran penyakit.

Bukan lagi teori atau asumsi, hal tersebut benar dialami seorang perempuan berumur 20 tahunan asal New York. Setelah melakukan terapi ikan, ia mengaku bentuk kukunya jadi aneh.

Dalam laporan kasus yang terbit di jurnal JAMA Dermatology, Selasa (3/7/2018), kuku kaki perempuan ini seperti terbelah, di mana bagian bawah kuku terpisah dari bagian atasnya. Anehnya, ia sama sekali tidak merasa sakit.

Dalam laporannya, ia mengaku tidak mengalami cedera kuku atau riwayat keluarga yang memiliki gangguan kuku. Ia melaporkan, sebelum masalah kuku muncul, dirinya sempat melakukan fish spa.

Dari kondisi tersebut, dokter mendiagnosis perempuan itu mengalami onikomadesis, yakni suatu kondisi di mana kuku terpisah dari matriks kuku atau jaringan di bawah kuku yang berfungsi menumbuhkan kuku.

Menurut American Academy of Dermatology (AAD), onikomadesis muncul karena sesuatu yang menyebabkan kuku berhenti tumbuh sementara waktu.

Pada akhirnya, pasien onikomadesis akan memiliki kuku yang cepat patah.

Kabar baiknya, onikomadesis tidak permanen. Dalam laporan di jurnal Cutis edisi 2017, pertumbuhan kuku dapat kembali setelah 12 minggu.

Banyak faktor yang dapat menyebabkan onikomadesis, termasuk infeksi, gangguan autoimun, obat-obatan, keturunan, dan faktor terbaru karena terapi ikan.

Selama terapi ikan, kaki akan dibenamkan dalam sebuah bak bersama air dan ikan air tawar kecil bernama Garra rufa. Ikan tersebut akan menggigit kaki dan memakan sel kulit yang mati.

Di habitat aslinya, ikan asal Timur Tengah memakan plankton.

Menurut laporan kasus ini, popularitas terapi ikan memuncak sejak satu dekade terakhir.

Sebelumnya para ahli telah memperingatkan, terapi ikan dapat menyebarkan penyakit dan infeksi.

Alasannya beragam, bisa karena bak yang tidak dibersihkan dengan baik atau ikan yang sama digunakan untuk pelanggan berbeda.

Menurut CDC, hal itu sangat mungkin untuk menyebarkan infeksi.

Bukti ilmiah

Berkat beberapa penelitian, praktik fish spa dilarang di AS.

Dalam temuan ilmuwan Inggris yang terbit di jurnal CDC Emerging Infectious Diseases pada 2012, diketahui ikan Garra rufa membawa sejumlah bakteri yang berpotensi berbahaya.

Seperti Vibrio vulnificus yang bisa menyebabkan infeksi kulit dan Streotococcus agalactiae yang dapat menyebabkan infeksi pada jaringan lunak.

Selain itu, ilmuwan Italia juga pernah melaporkan kasus infeksi kaki karena bakteri Staphylococcus aureus karena terapi ikan di tahun 2014.

Dalam kasus terbaru ini, belum diketahui bagaimana fish spa dapat menyebabkan onikomadesis. Ahli menduga, hal itu karena kuku mengalami trauma karena ikan menggigitinya sehingga membuat kuku berhenti tumbuh.

"Kasus ini menyoroti pentingnya masalah kulit dan kuku terkait fish spa dan kebutuhan dermatologis untuk mengedukasi pasien terkait efek buruk ini," tulis laporan itu seperti dilansir Live Science, Selasa (3/7/2018).
