The Sarcastic Fringehead is a bizarre-looking fish that lives at the depths of the northeastern Pacific Ocean, where it takes shelter in burrows or tube-like structures created by other creatures. The most striking feature is the large mouth that helps determine dominance. When two males compete for territory, they press their mouths together (almost like a kiss) to determine which is the larger fish. Smaller Fringeheads will often walk away without a fight. The female will then lay her eggs in the dominant male’s shelter so she can protect them. They seem to eat a variety of prey, including plankton and squid.
