Water-holding frogs are ectothermic, [8] meaning they depend on external sources of body heat. Aestivation is a behaviour characteristic of water holding frogs. It is similar to how other animals hibernate, except it takes place during summer as opposed to winter when weather conditions are hot and dry. This behaviour is a response to high ...
When met with a dry period, these frogs tuck their ventral areas under them so that only their resistant skin is exposed. They also secrete a water-resistant mucus to seal any small gaps when they aestivate. [12] [13] If disturbed and forced to move, they lose a significant amount of water and may not be able to survive the rest of the dry ...
Rheobatrachus, whose members are known as the gastric-brooding frogs or platypus frogs, is a genus of extinct ground-dwelling frogs native to Queensland in eastern Australia. The genus consisted of only two species, the southern and northern gastric-brooding frogs, both of which became extinct in the mid-1980s.
Most tree frogs are under 10 cm (4 in) in length, with long legs and long toes with adhesive pads on the tips. The surface of the toe pads is formed from a closely packed layer of flat-topped, hexagonal epidermal cells separated by grooves into which glands secrete mucus. These toe pads, moistened by the mucus, provide the grip on any wet or ...
Cuban tree frogs are the largest tree frogs in North America, ranging from 2 to 5.5 inches or (5 to 12.7 cm) in length. [8] Cuban tree frogs are mostly gray, brown, or green, with young frogs having more green coloration than adults. These frogs have rough, warty skin with blotchy or mottled patterning. [9]

Tree frogs typically have well-developed discs at the finger and toe tips, they rely on several attachment mechanisms that vary with circumstances, tree frogs require static and dynamic, adhesive and frictional, reversible and repeatable force generation; the fingers and toes themselves, as well as the limbs, tend to be rather small, resulting ...
Many poison dart frogs in the genera Oophaga and Ranitomeya carry their newly hatched tadpoles into the canopy; the tadpoles stick to the mucus on the backs of their parents. Once in the upper reaches of the rainforest trees, the parents deposit their young in the pools of water that accumulate in epiphytic plants, such as bromeliads .
