Sciades
Sciades is a genus of sea catfishes mostly found along the Atlantic Ocean and Caribbean Sea coasts of Central and South America. One species, S. dowii, occurs on the Pacific side from Panama to Ecuador, another, S. paucus, is a freshwater form found in Australia, while S. sona is a widespread species found along the Indian Ocean coasts of South Asia east into the Pacific to Polynesia. The genus Ariopsis has been merged with Sciades by some authorities.
