Ariopsis felis, commonly known as the hardhead catfish, inhabits brackish and coastal waters of the Gulf of Mexico and the Atlantic Ocean. It is easily identified by its flattened head, long barbels, and forked tail. Known for its resilience, it plays a vital role in coastal ecosystems as both predator and prey.

Ariopsis felis, commonly known as the hardhead catfish, is native to the coastal waters of the western Atlantic Ocean. Its geographical distribution includes the Gulf of Mexico and the eastern coast of the United States, stretching from Florida to Texas. It is also found along the eastern shores of Central America and parts of the Caribbean.

The hardhead catfish typically inhabits shallow coastal waters, including estuaries, bays, and river mouths. It prefers brackish to saltwater environments with sandy or muddy bottoms. The species is tolerant of a range of salinities, often found in areas where fresh and saltwater mix.

Ariopsis felis occupies an ecological niche as a bottom-dwelling scavenger and predator. It feeds on a diet of small fish, crustaceans, and invertebrates. The species plays a role in the ecosystem by helping to control populations of its prey and recycling nutrients through its scavenging activities.
