Oreosoma atlanticum

Oreosoma atlanticum, also known as the ox-eyed oreo, is a species of oreo found in oceanic deep waters. It is the only known member of its genus. Although adults are more similar in shape to other oreos, the juveniles have a distinctive plating/armor in their skin, which is spiked and probably makes them harder to eat for any hostile creature. Adults lack that plating, and, as other oreos, they have a protractile mouth and very large eyes, with small scales.
