Frog

A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek ἀν-, without + οὐρά, tail). The oldest fossil "proto-frog" appeared in the early Triassic of Madagascar, but molecular clock dating suggests their origins may extend further back to the Permian, 265 million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforests. There are approximately 4,800 recorded species, accounting for over 85% of extant amphibian species. They are also one of the five most diverse vertebrate orders.

The Frog in a Frog Could Give Treatment To Humans

Researchers are searching for this gastric brooding frog last seen in 1985. This frog is rare in its ability to swallow its egg and eventually give birth in its mouth. Very unusual! What is more interesting is that tadpoles develop in the absence of acidic digestive juices in the stomach of the frog, which could give doctors a new treatment for stomach ulcers for humans. Awesome! My microbiology class has peaked my interests in animals, that can contribute to treatments for humans.

Certain frogs can be frozen solid and still be alive after being thawed!

The Amazon horned frog has a reputation for eating everything in sight. Some have even died trying to eat prey larger than their bodies. This is one species that never learned portion control. By the way they are very territorial, so don't try to take this guy's pumpkin.

Hairy Wolverine Frogs

The hairy frog-- yes, a frog with hair-- has a defense mechanism in which it breaks its own bones in order to release pointy claw-like bones from their toe pads.

Although frogs can't empty their stomachs like humans do, they have an alternative method. They throw up their entire stomach then dig out the contacts with the forearms. After everything is out, they swallow their stomach back down and live life like before.
