Ariidae - Sea catfishes

The Ariidae or ariid catfish are a family of catfish that mainly live in marine waters with many freshwater and brackish water species. They are found worldwide in tropical to warm temperate zones. The family includes about 143 species.

Distribution and habitat
Ariids are found worldwide in tropical to warm temperate zones. Ariids are unusual among catfish in that they live primarily in the sea; the majority of catfish families are strictly freshwater and have little tolerance for brackish or marine conditions. Ariid catfish are found in shallow temperate and tropical seas around the coastlines of North and South America, Africa, Asia, and Australia.

Many other species of catfish are also present in freshwater habitats; some species only occur in freshwater. In North and South America, about 43 species extend into brackish water or are found exclusively in fresh water.
