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.

Frogs are hunters. One of the key behaviors of frogs is their habit of sitting completely still and awaiting their prey. They mainly hunt at night and lie in wait for appropriate prey, which consists largely of insects. Most frogs have long, sticky tongues that unfurl from the front of their mouths to snatch prey, which they then swallow whole. During the day, frogs tend to sit still in warm, dark, damp spots, as dampness and humidity help to keep their skin moist.

Frogs have a complex system of vocalizations that they use for communication, including distinctive mating calls and danger warnings. Breeding behavior depends heavily on climate. In warm, humid climates, breeding can occur at any time of the year. However, in colder areas, breeding occurs in mid-spring, after the temperatures warm and all danger of frost has passed.

Owners of pet frogs quickly come to learn their normal behaviors. If this behavior suddenly or inexplicably changes, this could indicate that the frog is unwell. In this case, it is advisable to seek the advice of a veterinarian.
