The elongate tonguesole (Cynoglossus elongatus) is a species of flatfish found primarily in the Indo-West Pacific, recognized for its elongated, slender body and preference for sandy or muddy seabeds in shallow coastal waters. This demersal fish is valued in regional markets for its mild flavor and is typically caught using trawl nets. The top countries engaged in harvesting elongate tonguesole are India, Bangladesh, Thailand, and Indonesia, where it forms an important part of local and commercial fisheries. These nations' fishing industries target tonguesole both for domestic consumption and export, contributing to livelihoods in coastal communities. The species is generally landed as part of multispecies trawl fisheries, and while not as globally prominent as other flatfish, it is regionally significant in South and Southeast Asia.
