• Freshwater

Habitat

Premontane and lower montane forest (1210-2040 m).

Call

A series of three "cheeps" (Savage 2002).

Breeding season

Males call from vegetation along the margins of streams throughout the year (Savage 2002). Breeding likely occurs year-round (Duellman 1970), but seems to peak at the beginning of the rainy season (Savage 2002). However, reproduction has not been observed (Savage 2002).

Egg

Gravid females contain 76-104 eggs (Lang 1995).

Tadpole

The tadpole is oval shaped, but somewhat compressed dorsally (Savage 2002). Tadpoles are brown with some gold flecking apparent (Savage 2002). The tail is light brown, with extensive dark blotching along the top and less pigmentation extending down onto the sides of the tail (Savage 2002). Tadpoles have a large suctioncup-like mouth that enables them to adhere to rock surfaces in fast-moving streams (Savage 2002).

Karyotype

2N = 24 (Leon-Azofeifa 1970)
