This Lavender Sculpin looks pretty cross, perhaps because I was watching his courtship with a large female at Tajiguas. (I am guessing at the sexes of the participants here). Lavender Sculpins are pretty common off the beach, usually on small sand areas surrounded by kelp. They often seem to be taking part in various kinds of romantic activity, sometimes in large groups. They are enthusiastic participants in the local club scene, and also enjoy cocktail parties, preferably chaotic ones.
