Although these frogs can swallow animals almost half their size, they sometimes attempt to eat things larger than they are. Their teeth, as well as bony projections in the front of the jaw, can make it difficult for them to release prey after taking it in their mouth, in some cases leading to death by choking.
Frogs can hear both in the air and below water. They do not have external ears; the eardrums (tympanic membranes) are directly exposed or may be covered by a layer of skin and are visible as a circular area just behind the eye. The size and distance apart of the eardrums is related to the frequency and wavelength at which the frog calls.
Pig frogs are opportunistic feeders and will eat a wide variety of prey, including insects, worms, and small vertebrates. Their primary diet is crawfish, but like most bullfrogs, they will consume almost anything they can swallow, including insects, fish, and other frogs. They are known to feed on beetles, dragonflies, crayfish, and other ...

Myobatrachidae, commonly known as Australian ground frogs or Australian water frogs, is a family of frogs found in Australia and New Guinea.Members of this family vary greatly in size, from species less than 1.5 cm (0.59 in) long, to the second-largest frog in Australia, the giant barred frog (Mixophyes iteratus), at 12 cm (4.7 in) in length.
The crab-eating frog (Fejervarya cancrivora) is a frog native to south-eastern Asia including Taiwan, [2] China, Sumatra in Indonesia, [3] the Philippines and more rarely as far west as Orissa in India. [4]
In the late 1960s, an expedition led by Jacques Cousteau reported Titicaca water frogs up to 60 cm (2 ft) in outstretched length and 1 kg (2.2 lb) in weight, [11] [12] [13] making these some of the largest exclusively aquatic frogs in the world (the exclusively aquatic Lake Junin frog can grow larger, as can the helmeted water toad and African goliath frog that sometimes can be seen on land).

Amphibians like frogs and toads can vocalise using vibrating tissues in airflow. For example, frogs use vocal sacs and an air-recycling system to make sound, while pipid frogs use laryngeal muscles to produce an implosion of air and create clicking noise. [7] Aquatic mammals such as seals and otters can produce sound using the larynx.
