Sedang menjadi viral sebuah foto ikan kecil dengan tubuh transparan dan tidak tampak organ-organ tubuhnya kecuali hanya sebuah ‘garis’ dari arah kepala ke ekor.
Beberapa netizen menduga-duga, mungkinkah itu sebuah mainan plastik bening yang menyerupai ikan?
Faktanya, mahluk kecil cantik tersebut adalah larva Surgeonfish. Larva ini disebut acronurus, biasanya hidup di laut dalam, disela-sela karang dan bebatuan.
Pada awal tahun 2014, larva Surgeonfish juga pernah ditemukan menyangkut di jaring para pemancing ketika mereka sedang menjaring tuna di Hurricane Bank off Baja.
Foto surgeonfish itu ditangkap oleh para pemancing, mereka awalnya tidak yakin jenis ikan hasil tangkapannya.
****Q****: We netted this little fish while scooping flyers on a recent big-tuna charter trip to the Hurricane Bank off Baja. We carefully placed it in the bait tank, though later it was released by some caring angler who was unaware that the crew had been thinking Hubbs Seaworld would want to have it. So we weren’t able to ID it, but some of us speculated it might be a baby opah. Any thoughts?Larry Brown — Playa Del Rey, California
A: Larry, I was kind of stumped by this one, although it did look kind of like a transparent surgeonfish. So I turned to tropical fish guys H.J. Walker and Ross Robertson, both of whom identified it as a larval surgeonfish. While the larvae of many fish species are small and tend to look like strings of snot with eyes, a surgeonfish larva (called an acronurus) is, as you can see, quite large and really rather handsome. H.J. noted that this was the largest larval surgeonfish he had ever seen — usually by this size the fish would be on the bottom, living over corals and rocks. As to what species you caught, it could either be an Achilles Tang (Acanthurus achilles) or the Whitecheek Surgeonfish (A. nigricans), both of which live over that tropical bank. — Milton Love
