Oyster Toadfish (Opsanus tau) Fish Description

The Oyster Toadfish are also commonly known as the ugly toad, oyster cracker, oyster catcher, and bar dog. They appear principally yellowish with an olive-brown back along with a pattern of brown blotches or sloping lines, and a pale belly.

They are scaleless and have a compressed, flattened body that can grow 12 inches lengthwise. Oyster Toadfish have “whiskers” or paunchy flaps on their cheeks and jaws. On top of their large, flat head are bulging large eyes accompanied by a broad mouth filled with strong, rounded teeth. They very much resemble a toad, as they are named.

But careful, Oyster Toadfish has a venomous spine on their first dorsal fin. Venom from the Oyster Toadfish has been compared to the pain levels of a bee or wasp sting.


Oyster Toadfish Diet and Size

Oyster Toadfish are omnivores. Their common prey includes the following: crustaceans, mollusks, amphipods, squid, and other smaller fish.

The length of the Oyster toadfish is about 17 inches and rarely do they grow longer than 15 inches.
