how frogs survive

Split in Half!


[Southern Leopard  Frog] Some frogs have developed neat ways to fool predators by stripes that appear to split them in two! The stripe down the scenter confuses predators from above by breaking up the outlines of "frog" shape to look like something different. This way, the frog or toad can blend in easier to it's background.

Poison Glands


[poison gland] Toads often have puffy looking pockets called paratoid glands located behind the ear that squirt poison at potential predators. So, if you've ever hear a dog "scream" after picking up an American Toad, now you know what happened! Although frogs have poisonous skin glands, these toxins do not usually protect them from predatory mammals, birds, and snakes. Edible anurans have to rely on more than just poison glands which tend to work too late (i.e. after the predator has it in his mouth!)

FLASH! Confuse Your Enemies


[Barred Leaf Frog] Some species have bright colours on their underparts or legs that flash when the frog moves, presumably confusing enemies.
The enemy gets distracted by the colors, then by the time they remember they were chasing a frog, our froggy friend has leaped away to safety!
This Barred Leaf Frog (Phyllomedusa tomopterna) has little stripes under it's legs that flash when it runs.
