Meet Peter, a giant anteater at the Santa Ana Zoo. Reaching up to 7 feet in length, these guys are the largest of the four anteater species. Without teeth, anteaters use their long tongues to catch and consume their prey. Their tongues can flick up to 150 times a minute, giving them the ability to gobble thousands of insects a day. Sadly, overhunting and habitat loss have left the species vulnerable.
