Frogs reproduce through eggs, which they lay in the water. These eggs hatch into tadpoles that later grow into adult frogs.
There is also a species of tree frog that uses nests that are built into the water so that the tadpoles are born directly in the water. A large group of frog eggs are called frog spawn because they have a gooey, slimy material connecting them together. The frog uses the gooey material to help the eggs reach the surface of the water because the material floats. Female frogs lay between 10,000 and 20,000 eggs.
Once the egg has hatched into a tadpole, then the tadpole has to go through the process of metamorphosis, which turns it into an adult frog. The exact length it takes for metamorphosis to complete depends on the frog species. Most frogs will need several weeks up to a year for the metamorphosis process. Some frogs need more than a year.
The lifespan of a frog is typically 7 to 9 years, but frogs can easily be eaten by predators such as lizards, birds and snakes. Frogs eat insects, fish, mice and even birds depending on what the frog species can fit into its mouth.Learn More
Though additional research is still needed, based on a study published in Volume 22, Issue 2 of the Electroencephalography and Clinical Neurophysiology journal, their observed behavior suggests that frogs do not sleep in the same way that mammals do. Many species of frogs are only active at night, spending the daylight hours sitting motionless in safe, moist hiding spots, such as under logs. However, rather than normal sleep cycles, the frogs observed seem to stay in a state of alertness during these "rest" periods.Full Answer >
Where frogs hibernate depends on the species, with terrestrial types burrowing underground or hiding in logs and rocks, and aquatic types hibernating underwater. Unlike some turtle species, aquatic frogs do not hibernate in mud below the water's surface. They are more likely to sit or periodically swim atop it.Full Answer >
How often a frog eats depends on his size and species. Generally, smaller frogs require daily feeding, medium-sized frogs must feed up to four times a week, and larger frogs need feeding a few times a week.Full Answer >
When it is time to mate, frogs assemble at a body of water. Males arrive first and call females to the site. In the reproductive act, the male mounts the female and fertilizes the eggs as the female releases them. In some species, the adults then abandon the eggs.Full Answer >
