South American rattlesnake (Crotalus durissus)

Crotamine is a toxin present in the venom of the South American rattlesnake (Crotalus durissus terrificus).

Common names for this species include: South American rattlesnake, tropical rattlesnake, neotropical rattlesnake, Guiana rattlesnake (previously used for C. d. dryinus).

The first myotoxin to be identified and isolated was crotamine, from the venom of Crotalus durissus terrificus, a tropical South American rattlesnake, by Brazilian scientist José Moura Gonçalves, in the 1950s.

The tropical rattlesnake can be found in sandy places or on dry hill sides.

The tropical rattlesnake is another important species.

Convulxin is a snake venom toxin found in a tropical rattlesnake known as Crotalus durissus terrificus.

Common names for this species include: South American rattlesnake, tropical rattlesnake, neotropical rattlesnake, Guiana rattlesnake (previously used for C. d. dryinus).

It has a high neurotoxic fraction that is antigenically related to Mojave toxin (see Crotalus scutulatus, venom A), and includes another component immunologically identical to crotamine, which is a myotoxin also found in tropical rattlesnakes (see Crotalus durissus).
