According to Wildlife Singapore, a frog croaks by forcing air out of its lungs and through its larynx. When air is forced through the larynx, the frog's vocal cords vibrate and create a croaking sound.Know More
Wildlife Singapore says the croaking sound that frogs make is amplified by vocal sacs, which are pouches under the floor of a frog's mouths. Frogs are able to amplify the sound of their croaks by keeping their mouths and nostrils shut. By using the muscles in their throats and the walls of their bodies, frogs can force air back and forth between their vocal sacs and their lungs. This is also the reason why the croaking of a frog is rhythmical.
According to Wildlife Singapore, male frogs are the only ones that croak. They use the sound to repel other male frogs from their territory and to attract females. Paw Nation says female frogs also emit a vocalization for breeding. However, the vocalization is very quiet and often cannot be heard over male frogs. A paper published in 1999 called “Brain, Behavior and Evolution,” shows that the mating call of a female frog is more similar to the release call that a male frog makes than to a male frog's mating call.Learn more about Frogs
Frogs breathe mainly by expanding their throat and opening their nostrils to allow air in, then contracting their throat to force the air into their lungs. Once the oxygen has been absorbed, the frog expands its throat to allow carbon dioxide from its lungs to its mouth, then opens its nostrils to let the carbon dioxide escape.Full Answer >
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 >
Frogs live on every continent except Antarctica. Frogs are typically found in warm climates because they are cold-blooded amphibians, although there are six species of frogs that live in climates with freezing temperatures. Frogs that live in climates with freezing temperatures belong to the families Hylidae and Ranidae.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 >
