HABIT AND HABITAT

Rhacophorus : Flying frog

GENERAL CHARACTERSTICS OF RHACOPHORUS-FLYING FROG

  • Commonly called flying frog or tree frog.
  • Body slender, divided into head and trunk. Belly narrows posteriorly, Females larger than males.
  • Head broad and somewhat conical containing paired eyes with well-developed eye lids. Tympanum behind eyes.
  • Hind limbs elongated and thin. Both fore-limbs and hind limbs contain well-developed web in digits which also bear adhesive cushions at tips.
  • The flying frogs climb on trees and walls and occasionally glide and while alighting on ground the webs are spread like parachute.
  • Eggs laid usually in gelatinous foam over shallow water of pools and rice fields.
  • upper limbs of the frog are green with small, scattered white spots. Faint black lines will sometimes radiate from its back to the dorsum of its limbs
  • Over forty species are currently recognised.

Special features

Rhacophorus shows extreme degree of adaptive radiation in frogs as it has acquired the power of flying or parachuting while alighting from trees. It shows parental care Rhacophorus schlegeli has evolved a novel technique to care for its eggs. The copulating males and females burrow deep into the ground on the bank of the standing pond. Eggs are laid in froth and parents retire through a tunnel they dig behind which slopes down to open in pond. The froth settles down and turns into a fluid shortly before larvae hatch and slip into the pond.

Identification

Since this Anura contains well-developed webs and above features, hence it is Rhacophorus or Flying frog.
