Frogs are a diverse and largely carnivorous group of short-bodied, tailless amphibians composing the order Anura (Ancient Greek an-, without + oura, 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 found in tropical rainforests. There are approximately 4,800 recorded species, making them among the most diverse vertebrate groups.

Famous quotes containing the word frog:
“A frog in love would not be enchanted to learn that her beloved had turned into Prince Charming.”
—Mason Cooley (b. 1927)
“What a wonderful bird the frog are
When he stand he sit almost;
When he hop, he fly almost.
He aint got no sense hardly;
He aint got no tail hardly either.
When he sit, he sit on what he aint got almost.”
—Unknown. The Frog (l. 16)
“Squats on a toad-stool under a tree
A bodiless childfull of life in the gloom,
Crying with frog voice, What shall I be?
Poor unborn ghost, for my mother killed me
Scarcely alive in her wicked womb.”
—Thomas Lovell Beddoes (18031849)
