Lonomia Obliqua
Most people don’t tend to second-guess picking up a cute caterpillar they find strolling through their gardens but this species in particular you may want to avoid. The Lonomia Obliqua contains a special toxin that’s released by its bristles when touched. The toxin is capable of blood hemorrhaging and brain death. However, in order to experience the full effect of this deadly defense system, a human “would need to be stung at least 20 to 100 times.”
