Crotalus durissus ruruima is a subspecies of venomous pit viper from Brazil.[1] It is restricted mainly to the savannah regions of Roraima, however it has been recorded in the Apiaú region possibly due to the deforestation of its natural range.[2]
Crotalus durissus ruruima displays a pair of dark stripes with lighter centers on its neck as well as a triangular head. It can be distinguished from other snakes by its specific scale count as well as its more conspicuous diamond pattern (with outlines of white) and 31.5 cm to 134.5 cm total body length.[2]
C. d. ruruima could display sexual dimorphism through its specific scale count as well as females being larger on average, however more research is required to definitively conclude this.[2]
Venom
Bites from Crotalus durissus ruruima are known to cause respiratory muscle paralysis, rhabdomyolysis, acute renal failure, pain, edema, myolysis, bleeding, uncoagulable blood and death.[2] It may present yellow or white, with the white venom showing more lethal, coagulant, myotoxic, edematogenic and hemolytic activity and the yellow variety showing hemorrhagic, necrotic and caseinolytic activities.[3]
