Interesting Facts About Frogs

Frogs – it amphibians that inhabit almost all parts of the world. They are found everywhere – in ponds or marshes, on the ground, even at a depth of several meters in a solid layer of clay on the trees.

This circumstance could not affect the species diversity of frogs.

These amazing amphibians are divided into three types: the actual frogs, toads and tree frogs.

Frogs have smooth or slightly lumpy skin, teeth, located on the upper jaw and swimming webbed hind feet.

The largest representative of the frog world – goliath frog (Conraua goliath). This giant frog can weigh more than three kilograms, its length is about 90cm. Strong foot-goliath frog enable it to make jumps to three meters in length.

The smallest frogs that live in Cuba, have a body length of 8,5mm to 12mm.

Toads unlike frogs, have no teeth. Toad skin thoroughly covered with tubercles, it is darker and drier than the skin of frogs. Behind the eye they are located well developed parotid gland. In general, the representatives of the family of toads prefer to live on land, going to the water only during the breeding season.

The largest toad in the world – it’s cane toad, it can weigh more than two kilograms. In addition, the cane toad – one of the most toxic among the toads and frogs. The smallest frog in the world has a length of 2,4cm.

Tree frogs – this is the small family among these three. Tree frogs are different from other types of presence of extended drives on your toes to help them climb up. Some types of tree frogs are able to “fly”, strictly speaking, it is not flying in the full sense of the word, and planning. This ability allows the frog to escape from the enemy, they can “fly” over a distance of up to 12 meters.

Most frogs have large protruding eyes, giving them almost 360′ vision. This is needed as they don’t have very flexible necks. They can see in colour and can have good vision for movement, even if far away.

Many frogs are nocturnal so have good night vision. They have a mirror layer in the back of the eye (called tapetum lucidium) that lets them reflect light at night,known as ‘eye-shine’. This gives them a kind or search light for hunting by.

Wet the skin of frogs has bactericidal properties. Our ancestors knew about it, throwing them into the milk, so it does not sour.

However, not all types of frogs are harmless. For example, a frog “Coco” that live in the jungles of South America, and Colombia, were recognized as the most venomous land animals on the planet. The poison of this frog is a thousand times stronger than potassium cyanide and 35 times more potent than the venom of the Central Asian cobra.

In Japan, the frog as a symbol of good luck.

In ancient Egypt, the frogs were the symbol of the resurrection, and even mummified along with the dead. This is probably due to the fact that many species of frogs that live in temperate and cold latitudes annually go into hibernation, freezing, and raised again in the spring. The fact that frogs produce antifreeze molecules – glucose. The fluid in the tissues from frost becomes syrupy, without forming ice crystals that allow amphibians to survive.
