Craugastor raniformis (Boulenger, 1896)

Craugastor raniformis is a relatively large frog species with a rather pointed snout.

Size and Sexual Dimorphism

Adult females of this species are much larger than males, reaching a snout–vent length of 52–74 mm (2.0–2.9 in), while males measure 27–43 mm (1.1–1.7 in).

Elevation and Habitat Range

This frog has been observed at elevations ranging from 0 to 1500 meters above sea level, in humid lowland and montane forests. It has also been recorded in pastureland, but is not commonly found in primary forest.

Protected Areas Within Range

Its known range includes multiple protected areas: Ranita Dorada Amphibian Reserve, Parque Nacional Darién, and Area de Manejo Especial Nusagandi.

Daytime Behavior

During the day, individual Craugastor raniformis stay hidden in leaf litter on the forest floor.

Nocturnal Climbing Behavior

At night, they may climb onto vegetation up to 2.5 meters above ground, or even higher. Males and juveniles climb more frequently than the larger adult females.

Male Vocalization

Males produce a call described as a "ha ha ha ha".

Reproductive Strategy

Like other species in the genus Craugastor, C. raniformis lays its eggs on land, and the eggs hatch directly into small froglets instead of a free-swimming tadpole stage.

Egg Guarding Behavior

Females of this species have been observed guarding their eggs; this guarding behavior likely protects the eggs from predators and fungi.
