Weird but true…it’s a fish

ANIMAL #5 Ipnops an unusual fish Creep into the Deep 640 x 469Hi Virtual Science Team,
Our Global Explorer ROV happened upon this very unusual fish called Ipnops. Those two bright yellow patches on the top of its head are its eyes.  It doesn’t have lenses, because those cut out too much light.  Basically, the eyes are naked retinas, with a layer of reflecting pigment below them, which is what gives it them that yellowish glow when you shine a light on it.
