Species Description

The Venezuelan Rattlesnake can be found in Colombia and Venezuela. It occurs in dry or semi-dry forests, savannas, the fringes of wetland praires and valleys, but can also occur as high as 6600 ft elevation. The Venezuelan rattlesnake's venom contains crotoxin, a neurotoxic venom component, in addition to nephrotoxins and myotoxins.

The venom of the Venezuelan rattlesnake has been shown to effective in inhibiting the growth of Candida, a fungus that causes yeast infections, and Sporothrix, a fungus that causes rose handler's disease. This can lead to the development of new antifungal medications as fungal diseases become resistant to our current treatments!
