Amazing natural comparisons. They can hit long and hard to crash into the memory. If, for example, visit the Museum of Natural History in New York, you can see the diversity of the world's fauna. There is presented the skeleton of a huge bird Moa, which reaches a height of about three meters. The giants themselves were already extinct, the last representative disappeared in the 19th century. And next to the moa is a tiny skeleton of a small hummingbird, inhabitant of South and Central America. And this contrasts do not end there.
The unusual exhibit, which is in the museum, belongs to a giant frog. They are more like the remains of a monster. And these are the bones of a squat and wide-boned frog Goliath, belonging to the genus Conraois. This is the biggest frog on the planet. The skeleton remaining in the museum is about one meter in size. But next to the goliath, the remains of a tiny cocoa frog are sheltered, these are jewelery fragile, tiny, the size of a thimble.
And so, what is known about champions
The goliath frog is the largest representative of 250 species of true frogs. Amphibians can be found to this day in the wilds of West Africa, namely, in Rio Muni and Cameroon. By the way, the local tribes of frogs are called rather affectionately “nia-moa”, which means “little sons”. Name them so, as the frog grows to the size of a one-year-old baby.
By the way, truly a miracle can be called an amazing device that allows the frog to stay on the surface of slippery stones that wash the rapid streams of water. And this device - suction pads, located at the very ends of the toes of the front paws only. However, the hind paws also help the choliath sit firmly on the stone - they have elastic membranes.
And the waterfall on Mbia-Riva, by the way, is very formidable, especially after heavy rains. Water cascades with a crash fall down and try to tear off the frogs firmly crouched on the stones.Well, where the water does not boil so much, frog females spawn. And each egg comes out the size of a whole pea. The frog breeds only during the dry season, for 5-6 days the female lays about 10 thousand eggs. The development of an egg to an adult being, that is, metamorphosis, lasts approximately 70 days. If at the moment of birth the tadpole has a length of only 8 millimeters, then after 45 days it grows to 48 millimeters.
However, the place of residence of the largest frogs in the world is not so safe. It fell under the close attention of man. This is because he tasted the taste of choliath meat. Therefore, the herd is constantly hunted and gradually destroy it completely.
But tiny Kokoa, a representative of amphibians, is the smallest frog. These dwarfs live in the pristine forests and jungles of Colombia. Even despite their miniature size, they will be able to stand up for themselves. Local Indians, who still use blowguns, risk their lives, but look for Cocoa, collect poison, which is excreted by the skin, moisten the tips of their arrows and go to hunt wild animals.
And the crystal poison, which was obtained from the alcoholic solution of the skin glands of cocoa, is ten times more toxic than the most deadly animal poison - puffer fish.
