Territorial Fish

The sarcastic fringehead is a bizarre looking fish that isn’t afraid to display its grit.


The sarcastic fringehead live off the coast of the Channel Islands. They make their homes in abandoned snail shells, and will defend their homes with all of the intimidation tactics they can muster.

If another fringhead gets too close, the two fish fight, with the more dominant specimen coming out on top.


Mouth Wrestling

What could loosely be described as “mouth wresting” the fringehead expand their jaws and attempt to intimidate the other. If bullying tactics don’t work, then things get physical. Darwinian rules apply, and the stronger one prevails.
