A type of small marine fish with armor-like bony plates covering its body, found in deep ocean waters.
From Greek 'amphi' (both) + 'sile' (possibly from 'silos' meaning armor or column), a genus name for deep-sea fish.
Amphisile fish live in the twilight zone of the ocean where pressure is crushing and it's nearly pitch-black, yet they've evolved these amazing bony plates that work like medieval knight armor underwater.
