Gloydius blomhoffii, commonly known as the mamushi, Japanese moccasin, Japanese pit viper, Qichun snake, Salmusa or Japanese mamushi, is a pit viper species found in Japan. It was once considered to have 4 subspecies, but it is now considered monotypic. This species, along with the yamakagashi (Rhabdophis tigrinus) and the Okinawan habu (Protobothrops flavoviridis), are the most venomous snakes in Japan. Every year, 2000–3000 people in Japan are bitten by a mamushi. Bitten victims typically require one week of treatment in a hospital. Severe bites require intensive care, and approximately 10 victims die annually. Wikipedia →
