Five species of marine turtle are reported to occur in the territorial waters of Bangladesh: the olive ridley (Lepidochelys olivacea), the green (Chelonia mydas), hawksbill (Eretmochelys imbricata), loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) (Ahmed et al. 1986; Groombridge & Luxmoore 1986; Rashid 1997; Rashid et al. 1999). Sea turtles were omitted from the list of protected species of the Bangladesh Wildlife Preservation Amendment Act, Schedule III, of 1974. Since 1980, according to anecdotal accounts, nesting populations have declined due to severe exploitation of eggs and illegal killing of adult turtles by fishing and other activities (Islam 1998). Today, few individuals nest on the sandy beaches along the coast of Bangladesh. This report gives an update on a population of nesting females during five seasons from October 1996 to June 2001 at St Martin's Island, Bangladesh.
