Frogs (it isn't actually a compo)

Frogs

Frogs are amphibians (an animal that spend the first part of their lives in the water and the second part on land) with slender bodies, smooth skins, strong legs, lungs, webbed feet, and no tail. Frogs use lungs for their breathing. Breathing is very special for frogs as there are no chest and breathing muscles. So, they have to breath by swallowing. Their heart consists of two entrances and one ventricle. Deoxygenized blood from the body comes to the right vestibule and then flows into the ventricle. The oxygenized blood from lungs comes to the left vestibule and flows to the one ventricle as well. This means that there is oxygenized and deoxygenized blood in the ventricle. Some of this mixed blood comes to the lung for oxygenation and another amount flows into the body circulation.

Frogs lay eggs in water. Here, the eggs hatch into tadpoles and breath with gills. Later on, gills are replaced by lungs and its tail drops of. Small tadpoles feed on plankton and vegetables while frogs feed on insects.

Tree frogs

The size of a tree frog is about 1.5 cm to 10 cm. They have got a bright green coloration with white or yellow ventral stripes, which may vary.
Tree frogs have strong and long legs. This lets them climb and jump. They are able to cling and walk on narrow branches, as well as jump up to 40 times their own length.

They usually hunt for food during the night. Reproduction starts when the males start to croak and call in order to attract females. Then the female lays eggs and the male fertilizes. This happens from mid April till mid August.

Red-Eyed Tree Frog

The Red-Eyed Tree Frog is a tree frog that sleeps during the day with their eyes closed and body markings covered. When they are disturbed, they flash their bulging red eyes and reveal their huge, webbed orange feet and bright blue-and-yellow flanks. This is called startle coloration. It might give a bird or snake a shock, offering a precious instant for the frog to spring to safety.
