Cochranella nola is a species of frog in the family Centrolenidae, the glass frogs, so named because of the transparent skin on the underside of the abdomen through which the internal organs can be seen. [2] This species is endemic to Bolivia where it is found in the Andean foothills in the Santa Cruz Department. Its natural habitats are subtropical or tropical moist montane forests and rivers. The scientific name nola is Latin for "small bell", and refers to the high-pitched, bell-like call of the male in the breeding season. [3]

Description

Cochranella nola is a small arboreal species of glass frog. Males are about 21 mm (0.8 in) long while females are a little larger at 25 mm (1.0 in). This frog has a truncated snout and vomerine teeth, widely-separated eyes and small, indistinct tympani. The dorsal surface and flanks are finely granulated while the hands and feet are smooth. The limbs are slender, the digits having adhesive toepads; there is extensive webbing between fingers III and IV, and between the toes. The dorsal surface and flanks of this frog are a uniform green with fine white speckling; the ventral surface is white, the hind part being transparent, enabling the yellow intestines to be seen. [4] The upper lip is white, the tongue is green and the iris is white, with dark reticulations, and a horizontal pupil. The bones are dark green. [4]

Distribution and habitat

Cochranella nola was first described in 1996 from the Santa Cruz Department in Bolivia, where it occurred near water courses in dry, semi-deciduous montane forests, damper montane forests and lowland rainforests, at altitudes between about 500 and 1,750 m (1,600 and 5,700 ft). [4] In 2013, the first record of its presence in Peru was recorded, it having been found in Bahuaja-Sonene National Park in the southeast of the country. [5]

Ecology

In the breeding season, males call from near fast-flowing streams, either from rocks in the streambed, or from foliage up to a few meters above the water. Up to six males may call in chorus, spaced out a few centimetres apart. The calls are either single high-pitched "pinks" at irregular intervals, or groups of three "pinks" in quick succession. Females lay clutches of eggs on wet boulders. [4]

Status

In its limited range in Bolivia, this species is common, but it is threatened by pollution of the streams where it breeds which can suffer from agricultural run-off, and the International Union for Conservation of Nature has rated it as "near-threatened". Now that it has been recorded from a further location in Peru, this frog's conservation status may need to be reassessed. [1]

Glass frog Family of amphibians

The glass frogs are frogs of the amphibian family Centrolenidae. While the general background coloration of most glass frogs is primarily lime green, the abdominal skin of some members of this family is transparent and translucent. The internal viscera, including the heart, liver, and gastrointestinal tract, are visible through the skin, hence the common name is given as glass frog. Glass frogs are arboreal, meaning they mainly live in trees, and only come out for mating season.
