The Zanzibar tonguesole (Cynoglossus zanzibarensis) is a demersal flatfish found in the shallow coastal waters of the Western Indian Ocean, particularly around East Africa, the Arabian Peninsula, and the Indian subcontinent. Recognized for its elongated, asymmetrical body and sandy coloration, this species inhabits muddy and sandy bottoms where it feeds on small invertebrates. The Zanzibar tonguesole is of regional commercial importance, primarily harvested by artisanal and small-scale fisheries using trawl nets and handlines. The top fishing countries for this species include Tanzania (notably around Zanzibar), Kenya, Mozambique, India, and Oman. In these countries, tonguesole is a valued source of protein for local communities and is sold fresh in local markets, with some catch also dried or salted for preservation. While not a major export commodity, sustainable management is crucial, as localized overfishing and habitat degradation can impact stocks and the livelihoods of coastal fishers dependent on this resource.
