The black-banded sea krait (Laticauda semifasciata), also known commonly as the Chinese sea snake or erabu, is a largely amphibious species of extremely venomous marine reptile in the subfamily Laticaudinae, family Elapidae (cobras, mambas, coralsnakes and their kin). It is found in much of the western Pacific Ocean and some of the Sea of Japan. In Japan, it is known as erabu umi hebi (ja:エラブウミヘビ, 'erabu sea snake'); in Okinawa, it is known simply as irabu. This sea krait frequents coral reef habitats, where it can explore tight spaces for prey, as it has a short head, thick trunk, and no easily discernible neck. The tail is simply extended skin, spread wide like a fin, and unsupported by any bony projections from the vertebral column. The stomach is comparatively wide. Massing together near the shore, it breeds between narrow cracks in the reef and in caves. It is a nocturnal snake, rarely seen during the day. It breathes air; so it breaks the surface at least once every six hours. Too slow to pursue prey in open water, black-banded sea kraits hunt primarily by exploring the small spaces within coral reefs, in an effort to find hidden fish or other appropriately-sized animals. This meticulous scouring of the narrow nooks and crannies within a reef is similar to the hunting behaviors of some of the sea krait's main prey choices, such as the moray eel. Additionally, the black-banded sea krait has been observed foraging in mutually beneficial 'alliances' with bluefin trevally; the sea krait will scour the reef for potential prey as waiting groups of trevally watch, ready to pick-off any smaller, unwanted fish or crustaceans that are inadvertently flushed from the coral. Additionally, this group hunting behavior has been observed to occur with other black-banded sea kraits. The bite is...
