Sarcastic Fringeheads: Aggressive Fish with a Unique Fighting Style

Sarcastic fringeheads are known for their unusual name and their extreme aggression. These small fish, found along the Pacific coast from San Francisco to Baja California, Mexico, live in shells or other underwater structures and defend their territory by yawning at each other. When males compete for mates, they engage in mouth-to-mouth combat, using their large colorful mouths to intimidate and dominate their opponents.
