Field Report Summary

Physical Description

Small fish, approximately 2 feet long, with a torpedo-shaped body. The body is covered in overlapping, bony scales similar to those found on ray-finned fish, rather than the dermal denticles of a typical shark. It has a cartilaginous skeleton and shark-like fins. The mouth is located underneath the head and contains rows of sharp teeth. The coloration is grey with darker grey spots. Gill slits are visible on the sides of the head.

Habitat

Deep-sea ocean environments.

Dietary Behavior

Preys on bony fish and crustaceans using venomous barbs.

Evolutionary Origin

Developed from a species of reptile which adapted its scales to survive on sharks. Evolved a symbiotic relationship where it eats parasites on the shark but also developed predatory habits towards fish.

Behavioral Notes

Secretes a potent neurotoxin from its scales, deterring predators and paralyzing prey.
