Frogs are amphibians that are renowned for there powerful jumping capabilities and sounds, from sonorous croaks to animated chirps. Frogs are actually one of the most diverse types of animal in the world with over 6,000 different species. Of all types of amphibians these frogs outnumber the combined numbers of salamanders, newts, and caecilians (which are long worm-looking creatures).
Frogs have a biological need to live in areas with plentiful water. This arises from the fact that they breed and lay their eggs in water. Aside from their need for water, they have few limits to where they may inhabit and they live virtually everywhere in the world, from Australia to North America. There is even a frog which lives in the sand dunes along the coast of Namibia and South Africa.
Frogs are a smaller and unassuming animal, but they will eat anything that fits in their mouth. This includes most insects, spiders, slugs, and small fish! They use their iconic tongue to disable and capture their prey. Their tongue moves at a remarkable speed, once launched they can pull their tongue back within 3/20 of a second. Their voracious appetite has, in some instances, caused them to be considered an economical way of dealing with pests, but they quickly grew out of control. For example, the Puerto Rican cane toad was introduced to Australia to help reduce the population of sugarcane beetles. The cane toads quickly switched to hunting native frogs, small marsupials and snakes.
