A frog's ear drum works in very much the same way as does a human eardrum. It is a membrane that is stretched across a ring of cartilage like a snare drum that vibrates. Crossing the middle ear chamber there is an ossicle called the columella that is connected to the tympanum, and another ossicle, the operculum, that connects this to the oval ...
Paedophryne amauensis, also known as the New Guinea Amau frog, is a species of microhylid frog endemic to eastern Papua New Guinea. [ 2 ] [ 4 ] At 7.7 mm (0.30 in) in snout-to-vent length , it was once considered the world's smallest known vertebrate .
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.
The northern cricket frog (Acris crepitans) is a species of small hylid frog native to the United States and northeastern Mexico. These frogs are majorly in grey, green, and brown color with blotching patterns. Many have a brown or orange stripe down the center of their back and a triangular marking on the top of their head.

A true endoskeleton is derived from mesodermal tissue. In three phyla of animals, Chordata, Echinodermata and Porifera (), endoskeletons of various complexity are found.An endoskeleton may function purely for structural support (as in the case of Porifera), but often also serves as an attachment site for muscles and a mechanism for transmitting muscular forces as in chordates and echinoderms ...
Chi You – A creature from Chinese mythology with the head of a bull, the torso of a human, and the ears and hindquarters of a bear. Cipactli – A creature from Aztec mythology that is part crocodilian, part fish, and part toad or frog.
Cricket frogs, genus Acris, are small, North American frogs of the family Hylidae. [1] [2] They occur in northern Mexico , the United States east of the Rocky Mountains, and in southern Ontario, Canada. [1] They are more aquatic than other members of the family, and are generally associated with permanent bodies of water with surface vegetation.
In reptiles, the columella function to transduce sound through the middle ear as part of the auditory pathway. The columella is relatively straight and moves in a piston-like motion in response to vibration. [3] Due to the rigid bony structure, the columella primarily responds to low-frequency vibrations transmitted through the ground. [2]
