Urutu

Bothrops alternatus
Nípa orúkọ náà: The scientific name alternatus is Latin for "alternating", apparently because of the staggered markings along its body. The common name urutu refers to the crescent markings on its body.1

The urutu is highly venomous. Its venom mainly contains phospholipase A2, snake venom metalloproteinases, snake venom serine proteases and C-type lectins. In one study of 32 patients, all had local pain and swelling, 97% had prolonged blood clotting, 41% had bleeding (usually from the gums), 32% had blistering and 9% had necrosis (death of tissue).1

Bites are an important cause of snakebite in its range and often cause severe local tissue damage, but they are rarely fatal. In a survey of 6,601 snakebite cases in Central and South America, 384 were attributed to this species, and 8 of those (2%) were fatal. Some bites have caused gangrene that required amputation, and in 2004 a 44-year-old woman died of a brain bleed after being bitten at home.1
