Gloydius tsushimaensis

Gloydius tsushimaensis (Gloydius tsushimaensis) is the Tsushima Island Pitviper, a venomous member of Viperidae with the stout body, broad head and facial pits characteristic of Gloydius. Identification should combine documented pattern, scalation, body form and locality because related Japanese reptiles may be very similar. Claims here are limited to the opened species accounts (Wikipedia, general species account; Reptile Database). Field identification should therefore remain cautious wherever photographs or diagnostic measurements are unavailable.

It is endemic to Tsushima Island in Japan; the opened account confirms its identity, venomous nature and restricted range while leaving unsupported ecology unstated. Information absent from those species-level sources is omitted rather than inferred from relatives. Japanese occurrence follows the site's catalogue and the opened distribution accounts (Wikipedia, general species account; Reptile Database). This conservative treatment keeps unresolved parts of its natural history clearly visible to readers.
