Foam-nest building behaviors and patterns have evolved several times. The foam nest made by the female provides different functions for aquatic and terrestrial breeding alike. Some grey foam-nest tree frogs breed exclusively in water. In these water-breeders, foam nests allow the eggs to be suspended in oxygenated water.
Chiromantis is a genus of frogs in the family Rhacophoridae, commonly known as foam-nest frogs or foam-nest tree frogs. [1] It contains species from the Sub-Saharan African tropics. [ 1 ] [ 2 ] Following the molecular genetic study by Chen and colleagues (2020), [ 2 ] the Asian species formerly assigned to Chiromantis have now been reclassified ...
Dwarf gourami bubble nest made of bubbles, floating plants and plant parts which were torn from a Hydrocotyle by the gourami male. Bubble nests , also called foam nests , are created by some fish and frog species as floating masses of bubbles blown with an oral secretion, saliva bubbles, and occasionally aquatic plants .
These frogs lay their eggs in aerial foam nests; upon hatching, tadpoles drop to the water under the nest and complete their development there. [3] [4] Some species like Rhacophorus kio will wrap this and cover this foam nest with leaves.
The camouflage mechanism used by the species provided compelling [6] evidence for evolution by natural selection.The zoologist Hugh Cott's drawings and description of the frog's "coincident disruptive coloration" showed that its pattern, forming bold stripes on the legs and body, lined up (coincided) exactly when the legs were tightly folded into the body at rest, effectively disrupting its ...

Chiromantis petersii is a species of frog in the family Rhacophoridae.It is found in Kenya and Tanzania and is broadly distributed in the inland areas of both countries. [1] [2] Chiromantis kelleri was previously considered subspecies of Chiromantis petersii, [3] but is currently recognized as a distinct species.
Although the reproductive strategy of this species has not been studied, members of the family typically make a foam nest while mating in vegetation overhanging a stream. They create the foam by beating their legs, and the eggs are deposited into the nest and covered with seminal fluid before the foam hardens into a protective casing.
