The Sarcastic Fringehead doesn’t let its small size deter it from aggressively lying in wait to attack anyone foolish enough to get too close to its home. Living in shells, crevices or the stray tin can or boot that finds its way down to the ocean floor, the Sarcastic Fringehead is very territorial and ferocious. If another fish, or even a human diver, comes within attacking distance, this vicious fish will spring, opening its mouth to its fullest size and baring its razor-sharp teeth. If this ever happens to you, it’s best to retreat quickly trying to outswim the angry little fish who will most likely chase after you.
These fish are usually around 6 to 8 inches, but they can grow up to a foot long, and they live mostly off the Pacific coast of North America. They’re more scientifically known as Neoclinus Blanchardi, but perhaps the more common name suits them better.
Watch the video below to see two Sarcastic Fringeheads going at it. Notice how they attack each other with their mouths. This way, they can determine who is bigger, and as a result, who wins the fight.
