Frogs are small amphibious tetrapods. Usually they are coloured brown, green, or yellow, but may be diversw colours in the tropics like red, blue, and black. Tropical frogs live in trees.

Life
Frogs use both gills and lungs during their life. Frog-skin looks glossy due to skin secretions, which are sometimes poisonous. Most frogs lack tails, and keep their limbs folded under their body. The fore feet have four toes and the rear feet have five toes. The toes stick strongly to wood, rock and glass. Frogs can only reproduce in fresh water. Frogs hatch from eggs and then become tadpoles. If not eaten first, tadpoles transform into adult frogs. Some male frogs make loud sounds with their mouths to make their presence known to females. Females choose their mates based in part on these calls.

All frogs eat small animals such as crickets, flies, bees, and worms. Their long sticky tongues hold fast to their quarry, preventing escape. Frogs are found on all continents except for Antartica, which is too cold for frogs.



Frogs are related to toads. Toads are much like frogs but with thick, dry skin. Some people believe that it is possible to contract warts from toads, but this is not true.
