Are there any poisonous mammals?
Venomous mammals produce venom, a poisonous chemical in their saliva. They use their venom to kill prey or to defend themselves against predators. They include the male duck-billed platypus, several species of shrews, and the solenodon, a nocturnal, burrowing animal that looks like a large shrew. Venomous mammals are rare: There are many more species of venomous reptiles such as snakes and amphibians. There are no species of venomous birds, however some birds are poisonous to eat or touch, such as the brightly colored pitohui and the ifrita. Both birds live in the rain forests of New Guinea.
