Frogs have no tail, except as larvae, and most have long hind legs, elongated ankle bones, webbed toes, no claws, large eyes, and a smooth or warty skin. They have short vertebral columns, with no more than 10 free vertebrae and fused tailbones
This is ironic that frogs have no tail but the original name the greeks had given them is translated to "animal tail"
The origin of the order name Anura—and its original spelling Anoures—is the Ancient Greek "alpha privative" prefix ἀν- (an-) "without", and οὐρά (ourá), meaning "animal tail". It refers to the tailless character of these amphibians.
This is how frogs got the name frog. It is interesting how it came from the greek language as many things we have. And how the name the Greek's had for frogs translates to "animal tail"
More than one third of species are considered to be threatened with extinction and over 120 are believed to have become extinct since the 1980s.
Frogs are dying and becoming extinct and it is a problem. Even in the amazon some frogs depend on the trees and the ecosystem to exist. If the trees are going away in fire it leaves frogs without a place to live.
Frogs are valued as food by human
This shows that frogs are used and seen completely different depending on the society and or culture. As in america they are pets and are not seen as food. However in France it is considered a delicacy.
. Adult frogs generally have a carnivorous diet consisting of small invertebrates, but omnivorous species exist and a few feed on plant matter
This shows the adult frog diet and how it is similar to the early frog's diet.
They have highly specialized rasping mouth parts suitable for herbivorous, omnivorous or planktivorous die
This shows that frogs eat a diverse amount of food. They eat other animals, bugs, they eat a whole variety of food.
Frogs typically lay their eggs in water. The eggs hatch into aquatic larvae called tadpoles that have tails and internal gill
This shows the early life of a frog and how it is born. It is important to know how frogs are born.
Their skin varies in colour from well-camouflaged dappled brown, grey and green to vivid patterns of bright red or yellow and black to show toxicity and ward off predators
Frogs will have different skin colors depending on the environment that they live in or to show they have poison and not to mess with them.
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
This shows how long frogs have existed.
A frog is any member of a diverse and largely carnivorous group of short-bodied, tailless amphibians
This is important as it sets down the ground base of what a frog is and separates the species from other amphibians and frog like similar animals.
