Hey hey, it's Lizard Tusday ! We're back on lizard track as today is about the Gila Monster: one of two venomous lizards to be found in North America. It's slow moving but the Gila Monster ranks as one of the many irrationally feared creatures. It's considered to be a living fossil because it hasn't changed much since the Pleistocene Age (and that's the last Ice Age, so they've been around for some time!). Their venom is kept in the lower jaw salivary glands; their teeth are not strong enough to project the venom so they poison by chewing. Gila monster are famous for bad breath-thought to be how they caught their prey-and in 2005 the US FDA approved a drug to manage type 2 diabetes make from Gila Monster spit.
