Opsanus tau, commonly known as the oyster toadfish, is a bottom-dwelling species found along the eastern coast of North America. It thrives in brackish and marine waters, often hiding among rocks and debris. This fish is known for its distinctive croaking sounds, camouflaged skin, and powerful jaws that help it feed on crustaceans and mollusks. It plays an important role in controlling the population of its prey species.

Opsanus tau, commonly known as the oyster toadfish, is native to the western Atlantic Ocean. Its geographical distribution includes the eastern coast of the United States, from Cape Cod, Massachusetts, down to Florida, and extending into the Gulf of Mexico.

The oyster toadfish typically inhabits estuarine environments and coastal waters. It is often found in shallow waters, such as bays, estuaries, and river mouths. The species is known to prefer areas with sandy or muddy bottoms and is commonly associated with oyster beds, which provide both food and shelter.

Opsanus tau is a benthic species, meaning it lives and feeds on or near the bottom of water bodies. Its ecological niche involves preying on small fish, crustaceans, and mollusks. The species is well-adapted to turbid and variable salinity conditions typical of estuarine habitats. It uses its camouflaged appearance to blend into the substrate, aiding in both predation and protection from predators.
