Range extension of parrotfishes Scarus zufar and Chlorurus rhakoura (Teleostei: Scarinae) to Bay of Bengal, Bangladesh

The Bangladesh coastline of the northern Bay of Bengal in the Indian Ocean, is predominantly a turbid, shallow, brackish-water-dominated shore with mostly muddy and sandy substrata (Longhurst & Pauly 1987). However, about 25 km of the circa 700-km coastline is partly rocky, including the tiny, about 8 km2, Zinjira Island (also called St. Martin’s Island), which is composed of sedimentary continental rock. The island is located about 10 km south of the southeastern corner of mainland Bangladesh, bordering Myanmar (Fig. 1). The island contains intertidal and subtidal rocky reefs which support live coral and seaweed communities.We report the occurrence of two parrotfish species (family Labridae, subfamily Scarinae), Scarus zufar Randall & Hoover, 1995 and Chlorurus rhakoura Randall & Anderson, 1997 in the area, beyond the known range for both species
