Cochranella granulosa

Cochranella granulosa

Grainy Cochran Frog

Taylor, 1949
  • Class: Amphibia
  • Order: Anura
  • Family: Centrolenidae
  • Group: Granulosa

Description

Small species (typically 25mm-30mm). Dorsal coloration is green often with tiny blue spots on the granular bumps, furthermore often the presence of larger black spots can be found scattered throughout the dorsum. Iris is gold, but at times with dark pigmented spots. Extensive webbing between fingers III-IV. The dorsum is covered in granules, thus giving the name "granulosa". The venter has a slight white parietal peritoneum, normally only covering the upper chest region. The digestive organs are covered in a white lining.

Distribution

Nicaragua, Costa Rica, and Panamá.

Habitat & Ecology

This centrolenid is nocturnal and riparian (found in the vegetation above and near streams).

Reproduction

This species reproduces along the vegetation overhanging streams, but one case of reproduction in a small forest pool located 2-3 meters from a stream has been observed (pers. obs. Parque Nacional Manuel Antonio, Puntarenas, Costa Rica 1998). The males typically call from above the leaves near and overhanging the stream. The advertisement calls are a rough high pitched trill or series. The dark eggs are deposited much in the same fashion as H. pulveratum, attached to the tip of the leaves, but are easily distinguished in being dark pigmented and having an extensive mass of jelly often larger than a golf ball.

Conservation

Status: Not Listed, but habitat destruction threatens amphibians worldwide.
