The black-banded sea krait, or Chinese sea snake (Laticauda semifasciata), known in Japan as erabu umi hebi (ja:エラブウミヘビ), and Okinawa as the irabu, is a member of the Laticauda genus of sea snakes. It is found in most of the warm waters of the western Pacific Ocean. Generally, the species is found in Fiji, southern Japan and Singapore. Their venom is ten times stronger than that of a cobra, making them extremely dangerous. Fortunately, this snake does not bite humans unless it feels threatened.
