Unidentified giant catfish-like species (Men in Black III)

This unnamed carnivorous ichthyoid species somewhat resemble catfish, used as food by at least some alien species.

Biology
Members of this species are giant, non-sapient, carnivorous ichthyoids, resembling Earth's catfish. However, they have four distinct nostrils in addition to gills, and sharp teeth. Additional features include brown and blue skin, six large, fleshy whisker-like appendages on the sides of their heads, large yellow eyes, multiple spike-like dorsal fins, and six fins, with four being located near their tails, while the other two are near their heads, and larger. Their nostrils are presumably used to sniff out prey, not to breathe, but condiments being sprayed into their nostrils can cause them to violently sneeze with enough force to send adult Humans flying. In addition, they have enough strength to throw Humans around with their tails and crush metal with their jaws. Being larger than a Human, large enough to swallow one, their gills are large enough for a Human to reach through. Near their gills, they have a heart-like vital organ. While aquatic, they can survive outside of the water for quite some time, and even clumsily manuever on land. They are known to remain rather docile in tight, enclosed tanks, but quickly turn aggressive if danger presents itself.
