Snapple’s “Facts” are usually wrong. I’ve proven quite a few already. Today’s Snapple fact says the Gecko is the only Lizard with a voice. Leopard Lizards are considered Iguanids. The Leopard Lizard, Gambelia wislizenii, can produce an aggressive vocalization which also means they have a voice. However, my favorite Gecko voice comes from the Tokay Gecko. Anyone who’s heard it will probably agree. They sound like they’re saying “TOKAY” which is how they obviously got their name.
