KYAAAAAAAAA!!!!

Halloween approaches!

Say hello to the sarcastic fringehead, Neoclinus blanchardi.

By opening its huge jaws and stretching out flaps of skin, the fish makes itself appear larger than it actually is.

The jaws are larger in males, which they use in intimidating displays to defend territory, guard eggs, and in rival bouts with other males (the responsibilities of being a manly-man, right?).

These guys can be found off the coast of California, residing in burrows, empty bottles, vacated shells, or under rocks.

Although they can be aggressive and intimidating, sarcastic fringeheads usually grow to only about 1 foot in length, so you are in no danger.
