Biter

The Biter Fish is an in-development life form that can currently only be spawned using the Debug Console Command "Spawn Biter".

A model of the Biter Fish, labeled as "Red Piranha", is on Sketchfab. Biter Fish animations can be found here.

Appearance
The Biter Fish is a small red and blue fish that strongly resembles a tadpole. It has two eyes on each side of its head, and a little mouth full of jagged yellow teeth. The Biter Fish has no pectoral fins, possessing only dorsal and tail fins. It also has a short Bioluminescent lure on its forehead, which is presumably used to draw in prey.
