Crotalus durissus cumanensis is a subspecies of venomous pit viper from Colombia and Venezuela. [1] They account for 1-3% of all snake bites in Colombia. [2] [3] [4]

Toxin

A bite from Crotalus durissus cumanensis can cause neurotoxicity, systemic myotoxicity, mild edema, acute renal failure and death, [2] [5] even considered one of the most lethal snake species in Latin America. [6] These bites are only treatable by antivenom therapy. [3] The toxin is thought to be more potent than that of Crotalus durissus ruruima . [7]
