Through this pattern, few individuals calls are drowned out. One frog's call may be dominant and trigger the calls of the responding frogs in symphony. Calling is linked to physical size and females may be attracted to more vigorous calls. [4] Frogs in the same region chorus within their species and between different species.
Theloderma corticale (common names: mossy frog, [3] Vietnamese mossy frog, [4] Tonkin bug-eyed frog, moss bug-eyed frog, [2] and [for the formerly recognized Theloderma kwangsiense] Kwangsi warty treefrog) is a species of frog in the family Rhacophoridae.The theloderma corticale is often difficult to identify visually as there are cryptic species that look very similar to it.

It has acquired a number of popular nicknames, including hippo frog , [ 3 ] Freddy Krueger frog , [ 3 ] and escuerzo de agua .
Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes , anteriorly-attached tongue , limbs folded underneath, and no tail (the tail of tailed frogs is an extension of the male cloaca).
The vocal sac is the flexible membrane of skin possessed by most male frogs and toads. The purpose of the vocal sac is usually as an amplification of their mating or advertisement call. The presence or development of the vocal sac is one way of externally determining the sex of a frog or toad in many species; taking frogs as an example;
The grey foam-nest tree frog typically has a snout length of 50–80 mm. Males have a snout-vent length of 43–75 mm, while females have a 60–90 mm snout-vent length. [2] They have relatively impermeable skin, which allows them to survive dry spells under tree detritus.
The next time you declare that you are “freezing to death,” spare a thought for the wood frog who gets so cold in winter that its heart stops beating – but it does not die. Once the spring ...
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 ...
