Bioluminescent Barbeled Dragonfish!

This beauty (a.k.a. Idiacanthus) lives about a mile deep underwater. They have weirdly stalked eyes as baby larvae (A) and the stalks somehow disappear as they mature (B). Almost nothing is known about their reproductive habits (how, when and where), but you can see that they dine on jellyfish (look inside B’s throat). Idiacanthus live in all the oceans of the world. These gorgeous pictures were taken by Dr. Christina Wahl and appear in her book, Morphometrics.
