#bothriopsis

(Bothriopsis taeniata) speckled forest-pitviper No specific venom data; however, the rather large size & long fangs of this snake make it potentially dangerous. Bothriopsis venom is primarily hemotoxic. 

(Bothriopsis punctata) Chocoan lancehead Venom not well known, but probably hemotoxic w/ cytotoxic factors, much like most Bothrops species. For generalized symptoms of envenomation, see the closely-related species, (Bothrops asper).

(Bothriopsis punctata) Chocoan lancehead

Based on its size, this snake is probably capable of delivering a fatal bite. Although it does not seem to be common anywhere, Ayerbe (1990) states that, in the regions where it occurs, it is the most dangerous species together with the common lancehead,Bothrops atrox. Angel-Mejía (1987) mentions a bite victim who was treated in Medellín for acute renal failure.
