Clinotarsus alticola[2][3] is a species of frog in the family Ranidae. Common names for this species include: Assam Hills frog, Annandale's frog, pointed-headed frog, palebrown stream frog, hill frog, point-nosed frog, and high-altitude frog. It is found in Hills of Meghalaya and northeastern India (Assam, Meghalaya, Mizoram, Nagaland, Tripura, and West Bengal) to northern Bangladesh, possibly into Bhutan and Nepal.[4]
Habitat
Clinotarsus alticola inhabit evergreen forests near large streams (the habitat for their tadpoles) in hill areas, usually near waterfalls.[1]
Description
Clinotarsus alticola are sexually dimorphic: males are 32–47 mm (1.3–1.9 in) in snout–vent length and females 43–61 mm (1.7–2.4 in). The advertisement call of males is a bird-like "chirp". In breeding sites, males greatly outnumber females and attempt to dislodge one another from the backs of females. Outside the breeding season adult Clinotarsus alticola are rarely encountered.[5]
The tadpoles of Clinotarsus alticola are distinctive: they are large (up to 98 mm (3.9 in) in length), have many glands, and are black in colouration with red ocelli. The caudal ocellus is a unique feature among ranid tadpoles. Its colouration may be aposematic.[6]
