How do frogs breathe underwater?
A frog’s eyes & nostrils are located on the top of their heads so they can breathe (and spot predators) while the rest of their bodies is hidden underwater. Do you know that frogs have slime covering their bodies? It keeps the frogs skin from drying out. Frogs eyes are big because sight is their major sense that they use the most. http://library.thinkquest.org/5486/frogs.
