Frogs inhabit a variety of different habitats and have a diverse array of predators and prey, but most frogs fill the small, ectothermic, insectivorous niche. Some frogs fill this niche in terrestrial ecosystems, but others do so in aquatic or arboreal habitats. Because they consume many small invertebrates and are themselves food for many small- and medium-sized predators, frogs are very important components of the ecosystems in which they live.Know More
Frogs that live in aquatic habitats generally consume insects and other aquatic invertebrates, such as crawfish. Additionally, large aquatic frogs often eat fish and other frog species. Snakes, predatory fish and raccoons, among other predators, predate upon aquatic frogs.
Some frog species have left the ancestral aquatic habitat and ventured into terrestrial and arboreal ones. This changes their ecological niche slightly, as they encounter different predators and prey. Most terrestrial frogs consume large terrestrial insects, such as roaches and beetles; however, some species, such as narrow-mouthed toads, specialize on small insects, such as ants and termites.
Arboreal frog species tend to eat flying insects common in their treetop habitats. Both terrestrial and arboreal frogs must avoid similar predators, including medium-sized birds, snakes, bats, foxes, opossums, and domestic dogs and cats.Learn more in Frogs
A frog's skeleton is divided into four major sections: the skull, the spine, the forelegs and the legs. While a frog's arms and legs are similar to those of a human, its skull and spine are markedly different.Full Answer >
Baby frogs will eat any small insects, snails or even tadpoles. A baby frog has a varied diet and will eat any animal as long as it is small enough to digest.Full Answer >
Although amphibious frogs live on land and in water, they must lay their eggs in water or the eggs will dry up, effectively killing the offspring inside. Frog eggs are covered with a glycoprotein, which helps keep the eggs moist. This glycoprotein has to keep in contact with a source of moisture, such as water.Full Answer >
