This terrible Lonomia caterpillars live in the rainforests of South America, and cause a few deaths every year, especially in southern Brazil, where they’re usually found on the bark of trees. Blending perfectly in their surrounding, Lonomia obliqua caterpillars often can’t be avoided, even if people watch out for them. Most incidents occur when travelers lean against a tree and unknowingly brush against one of more caterpillars, which release a very powerful anticoagulant venom.

Symptoms of Lonomia obliqua poisoning include severe internal bleeding, renal failure and hemolysis. If the skin comes into contact with several caterpillars, death is often the outcome. The lethal dose of the toxin secreted by this terrible creature is among the lowest of all known toxins.
