Some-fin Spooky for Halloween at SeaWorld San Diego!

With Halloween just around the corner, we thought we’d share some cool information on our spooky-looking, FINe friends (See what we did there?) here at the park! These bony fishes will definitely pique your interest.

The Wolf Eel

Wolf eels can be found along the Pacific coast of North America from northern Baja California, Mexico to Kodiak, Alaska west to Russia and south to the Sea of Japan. They are found in temperate and cold shallow waters usually in rocky areas. An adult wolf eel can reach a maximum length of up to 8 feet and weigh up to 41 pounds.

The Ghost Fish

These fishes are named for their transparent skin and muscle tissue. Look closely to see their bones and some internal organs, such as the swim bladder which helps them maintain buoyancy. The transparency may be helpful in camouflaging these fishes from predators.

The Four-Eyed Fish

The four-eyed fishes (family Anablepidae) swim at the water's surface. Their eyes lie at the water line and are adapted for seeing in air and in water. Separate retinae and an asymmetric lens allow these remarkable fish to focus on images above the water and on images under water simultaneously.

The Blind Cave Fish

Some species of bony fishes have no eyes. This includes the blind cavefishes. (family Amblyopsidae) They do not have vision perception, so they depend on other senses to help them find prey.
