The oyster toadfish, Opsanus tau, is a fish of the family Batrachoididae. The maximum length of the toadfish is about 38 cm; the most common recorded length of an oyster toadfish is about 30 cm. They are generally brown or yellowish with a pattern of brown oblique bars.


The species can live in poor conditions and needs little food to live. It is an omnivore. Common prey include crustaceans, mollusks, amphipods, squid, and other smaller fish. Toadfish rely upon camouflage to catch their food; they lie motionless waiting for prey to pass close by, then attack by surprise. They can be found from Maine to the Caribbean Sea.

The fish has a distinctive "foghorn" sound used by males to attract females in the mating season, which is April-October. The sound-producing (sonic) muscles attached to its swimbladders are the fastest known vertebrate muscles. Following the foghorn sound, the female comes into the nest, lays eggs, and then leaves (the toadfish lays the largest eggs of any Chesapeake Bay fish). The male fertilizes the eggs; they hatch after about one month. When the eggs hatch, the young toadfish stay attached to the yolk for some time. When the yolk has been absorbed for energy, the young toadfish learn to swim. Even when the young have started to swim, the adult still protects its young.
