Ominous and obscure animals at the Seattle Aquarium

Just in time for Halloween, here’s a peek at some of the creepy creatures on exhibit at the Seattle Aquarium. Get to know them here, then come check them out in person during your next visit!

Creeping pedal sea cucumber

Creeping pedal sea cucumber, Psolus chitonoides

This scaly echinoderm can be found creeping along in our Puget Sound Fish and octopus exhibits. It uses its oral tentacles to ensnare detritus floating in the water; however the tentacles themselves contain a toxin to deter any potential predators of the cucumber itself.

Sablefish

Sablefish, Anopoploma fimbria

Something about those beady eyes makes this fish look a little creepy! But many find it mightily tasty too—and may know it by its other common names: butterfish and black cod.

Red brotula

Red brotula, Brosmophycis marginata

This deceptive fish is longer than it appears and uses slime to protect itself from predators. Although unknown to many visitors, it’s been living in our Puget Sound Fish exhibit for over 10 years. A recent den rearrangement makes its hiding place slightly more visible.

Spotted ratfish

Spotted ratfish, Hydrolagus colliei

This cartilaginous fish is a marine-world Frankenstein, appearing to have the head of a rabbit, the body of a fish and the tail of a rat. There are dozens of species of ratfish in the Order Chimaera. In Greek mythology, the Chimera was a monster with the head of a lion, body of a goat and tail of a serpent. Other names for ratfish include ghost shark and spookfish. Learn more about them here!

Devil scorpionfish

Devil scorpionfish, Scorpaenopsis diabolus

This motionless, amazingly well-camouflaged fish could easily sneak up and scare you. With venomous spines, a downturned mouth and those eyes—there’s just something about them!
