ALL GLORY TO THE HYPNOTOAD!!! The Sonoran desert toad (Bufo alvarius), also known as the Colorado river toad, is one of the largest toads found in North America, measuring nearly 7 inches (18 cm). Will it hypnotize you with its large oscillating multicolored eyes? That’s just silly….MUST SHARE TOAD FACTS!!! What sound does it make? Its call has been described as a “weak, low-pitched toot, lasting less than a second.” Ooops! Pardon me. These toads have prominent parotoid glands that secrete a potent toxin. It can make you sick if you handle the frog or get the poison in your mouth. As we say with most things you come across in a national park, whether it be a banana slug, unfamiliar mushroom, or a large toad with glowing eyes in the dead of night, please refrain from licking. Thank you. Oops. Toot! Image: HYPNOTOAD SAYS YOU WILL BUY THE EXTENDED WARRANTY!
