Frogs primarily croak to advertise their fitness to perspective mates. The males are responsible for the vast majority of the croaks heard in a typical chorus, but the females of some species can also create vocalizations. When a female hears a frog with an attractive call, she approaches him and allows him to mount her and achieve amplexus.Know More
Every species of frog has a distinctive call. This allows males and females of the same species to find each other, breed and produce viable offspring. In fact, some frog species are visually identical, and they were thought to be a single species until their calls were analyzed, indicating that two species were masquerading as one.
Sometimes, an over-anxious male grabs another male and attempts to breed with him. When this happens, the male mistaken for a female then produces something called a release call. Release calls instruct the mounting frog that he has mistakenly grabbed an inappropriate mate.
Some frogs also make vocalizations when they are grabbed by a predator. This is called a predator call, and both sexes are capable of producing these sounds. Such sounds are thought to startle the predator, or in the case of snakes and other animals that cannot hear, attract secondary predators. These secondary predators may attack the primary predator, allowing the frog to escape.Learn More
Frogs typically eat insects and make frequent vocalizations. These behaviors are common to all frogs but vary according to species, seasons and the local environment.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 >
All frogs begin their lives as tadpoles that breathe underwater using their skin and gills. As the frog grows, lungs begin to develop and the frog loses its gills at it begins to metamorphose.Full Answer >
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 >
