Raorchestes chalazodes

Raorchestes chalazodes is a nocturnal and arboreal species found in the understorey of tropical moist evergreen forest and is endemic to the Western Ghats of India.

[2][3] The specific name chalazodes is composed of the Greek word χάλαζα (chalaza) meaning "lump" and -odes for the derived adjective, reflecting white granulation of the body.

Raorchestes chalazodes make their oviposition sites in the internodes of the Ochlandra travancorica species of bamboo, where the adult male will take care of the egg clutch.

[6] Raorchestes chalazodes is found in the narrow region of the Western Ghats on the West Coast of peninsular India, where they are restricted to elevations over 1200 m.[9] It lives in the tropical and moist evergreen forest understory.

[1] Raorchestes chalazodes is currently classified as vulnerable by the most recent assessment by The IUCN Red List of Threatened Species in 2023.

The frog also faces some threat from the annual pilgrimage to Agasthyamala Biosphere Reserve, in which pilgrims leave behind litter and collect firewood.

[1] The Ochlandra travancorica species of bamboo that Raorchestes chalazodes uses for oviposition sites is often harvested for use for biofuel and the manufacturing of paper and pulp.

[10] In a study on Raorchestes chalazodes in 2018, 43 egg clutches with male guardians were found in 5 km2 sampling site at Kalakad Mundanthurai Tiger Reserve.

[9] To help with conservation, a mapping of Ochlandra travancorica distribution to identify threatened areas that are not under protection is a vital first step of action.

Specifically, Raorchestes chalazodes was observed consuming Satiella dekkanensis, a type of snail that does not possess a hard shell.

Before the breeding season, adult male frogs will forage for large prey such as Satiella dekkanensis to prepare for the long period of caregiving.

[12] After the mating season ends, which is the months of November to December, the males will stop vocalizing and vacate the oviposition sites inside the internodes of the bamboo.

The main cause of predation is cannibalism from conspecific males who are thought to be unsuccessful in finding a mate and defending their own oviposition site.
