Southern Toad
Anaxyrus terrestris
What you should know
Southern toads have dry, bumpy skin and two large lumps behind their eyes called parotoid glands that make a milky poison to protect them from predators. If you touch a toad and then rub your eyes or put your fingers near your mouth, you could feel a burning or sick feeling. Always wash your hands right away if you touch one.
Whoa
Toads never drink water through their mouths. They soak up all the water their bodies need through a special thin patch of skin on their belly called the drinking patch.
Staying safe around it
This one is poisonous, which means it hurts you if you touch it or eat it. It cannot chase you, so the rule is simple: look, do not touch.
Always ask a grown-up before you touch any animal or plant. If something bites or stings you, tell an adult right away.
