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.
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.
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 ...
The foam is made from proteins and lectins, and seems to have antimicrobial properties. [181] Several pairs of frogs may form a colonial nest on a previously built raft. The eggs are laid in the centre, followed by alternate layers of foam and eggs, finishing with a foam capping. [182] Some frogs protect their offspring inside their own bodies.
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.
Most hyperoliids lay their eggs in water, although foam nesting, tree-hole breeding, and laying eggs in vegetation above water are all known behaviors. [2] Afrixalus builds leaf nests for its eggs, by folding and gluing the edges of the leaves.
The larvae in the foam nests are largely protected from predators and also get the necessary moisture for the appropriate development and temperature, so their mortality remains low even in bad weather. The larval stage lasts about 50 days. The adults leave the foam nest only when it is completely dried. This takes about ten days.
Rhacophorus is a genus of frogs in the shrub-frog family Rhacophoridae, which, with the related Hylidae, is one of the two genera of true tree frogs.They are found in China, India, Japan, and throughout Southeast Asia, including the island of Borneo.
