[null and void]

It's a little spiny parasitic catfish.

Normally it follows little currents of ammonium tainted water to home in on other fish's gills. There it will hook in with its spines and feast on gill tissues and blood.

It's small enough to swim into a urethra...

OOF....That I understand...a big little swimmer to keep company with the little ones...
