Description General Info
Description
Vipera berus sachalinensis displays adaptive behaviors reflection its cold, island habitat. Hibernation is extended (October to April), while mating occurs immediately post-awakening to maximize offspring survival. Vipera berus sachalinensis exhibits unique sexual dimorphism in venom composition, rendering males more toxic than females—a trait theorized to enhance male competitiveness during mating periods. Its primary role in the ecosystem revolves around small mammal population regulation and as a food source for larger predators.
