Slimy sculpins, Cottus cognatus, hidden members of the stream underworld.
Slimy sculpin (Cottus cognatus) are equipped with a battery of defense options which include concealment in the substrate, cryptic coloration, cryptic movement and darting. Sculpins live in close proximity to predators which puts a premium on their capacity to cryptically change color and blend into...
