For example, if eaten, puffer fish can prove deadly to humans because Homo sapiens are lethally allergic to the fish’s flesh.

Do reptiles have venom?

Some lizards possess a venom gland; they form a hypothetical clade, Toxicofera, containing the suborders Serpentes and Iguania and the families Varanidae, Anguidae, and Helodermatidae.

What are the major groups of venomous animals?

What are venomous snakes used for?

Venomous snakes are a species‐rich (~2500) group of squamate reptiles that are widely distributed across most of the Earth’s landmasses and many of its oceans (Greene, 1997). These snakes primarily use venom for facilitating prey capture, although when threatened or provoked they use venom defensively, as observed in cases of human snakebite.

What is the difference between Poison and poisonous organisms?

Poisonous organisms don’t deliver their toxins directly; rather, the toxins are induced passively. A poisonous organism’s entire body, or large parts of it, might contain the poisonous substance, and the poison is often created by the animal’s specialized diet.
