Cowfish and Trunkfish

The brightly colored Cowfish doesn’t have a skeleton. Like other trunkfish, his body is made of bony plates that fuse together in a boxy shape. The bony box is so rigid that trunkfish can move only their fins, eyes, mouth, and tail.

Cowfish can grow up to 12 inches long, and have a short spine over each eye.

Smooth Trunkfish also have a body of bony plates, and are closely related to the Cowfish. They are incredibly cute and fun to watch while you’re diving.

Trunkfish eat small crabs and shrimp off of rocks and coral. They also find food by spitting jets of water into the sand.

Cowfish and Trunkfish are featured in the Flat Cay West segment of Diving St. Thomas - Volume 1.
