Organism of the Week - Sarcastic Fringehead
The sarcastic fringehead, or Neoclinus blanchardi, is in the Animalia kingdom, Chordata phylum, Actinopterygii class, Perciformes order, and Chaenopsidae family.
Sarcastic fringeheads are described as small, but temperamental fish with very large mouths. They are most commonly 7.6 to 29 centimeters (3 to 8 inches) in length but they can reach 30.5 centimeters (12 inches). They can be brown or gray with a red tinge and green or pale marks. They have large heads with an extremely large jaw that extends past their eyes. In their giant mouth, they have many sharp teeth. They use their mouths and teeth to scare away and intimadate possible danger. When two fringeheads encounter each other, they open their mouths and bump into each other. If one of the fish does not leave, they will attack each other with their teeth. The sarcastic fringehead diet is unknown, but biologists believe that they eat smaller fish and crustaceans like the fish they are related to such as the flagblennies and tubeblennies.
Sarcastic fringeheads are found in the waters of the Pacific coast of North America. They live in burrows such as logs, shells, cracks in rocks, or even trash thrown into the ocean. These fish are extremely territorial and will attack anything near. They rest with their heads out of their shelter, allowing them to be aware of any possible intruders near. If they are threatened, they use their large mouths, showing their sharp teeth to intimidate the animal. If intimidation doesn’t work, they will attack.
Breeding occurs between January and August. Fringeheads are oviparous, meaning that the females lay eggs that hatch. The female lays about 3,000 eggs under rocks or in clam burrows, protected by the male. The eggs are about 0.9 to 1.5 millimeters (0.035 to 0.06 inches) in diameter and they stick together and to the nest by filaments in the egg. When the egg hatches, the larvae are about 3 millimeters long (.12 inches). Sarcastic fringeheads live up to six years.
Fun Fact: The name ‘sarcastic’ is used from the Greek definition meaning “to tear flesh.”
