[Eleutherodactylus ranoides (Cope, 1886)] |
Adult: Species description based on Savage (2002). Males are much smaller than females. Males reach lengths of 45 mm, females, 74 mm. Dorsal: Dorsal coloration varies from olive green to olive brown. Darker spots or blotches are usually present. The dorsal surface may be smooth or slightly bumpy. The upper surfaces of the arms and legs have dark bars. Ventral: The ventral surface is smooth and yellow. Concealed surfaces: Rear surfaces of thighs are dark brown, with many small light spots. Eye: The upper half of the iris is golden, the lower half brown. Habitat: Lowland and premontane wet forest to 1220 m. Craugastor ranoides may also be found at some drier sites (Puschendorf et al 2005, Savage 2002). Ecology: This species is often found near smaller streams (Savage 2002). It jumps into the water to escape threats (Savage 2002). Call: This species has no vocal sac and probably does not call (Savage 2002). Karyotype: 2N = 20 (DeWeese 1976) Type locality: Nicaragua Diagnostic description: Common, from small to moderate size (males 26-45 mm, 40-74 mm plug); back to smooth the grainy, dark olive to olive coffee, the uniform stained with dark pigment; vientre smooth, pale yellow to golden bright; Muslera surface it later marked with dark points clear small and discrete (Savage 2002). Habitat: It is a species associated with streams in wet and dry forests (gallery forests) (Savage 2002). Reproduction: Produce encapsulated eggs, which are laid in terrestrial conditions; development is direct (no tadpoles) (Savage 2002). Behavior: It feeds at night and jump over the water when disturbed (Savage 2002). Distribution in Costa Rica: In the lowlands and middle of the Atlantic Basin, 1-116 m elevation, and the Pacific slope, 10-1300 m elevation in the north and 500-1220 m in the south; absent in the Golfo Dulce region (Savage 2002). Populations of this species throughout its range disappeared in Costa Rica in the early 90's. We only have record of a surviving population in the Santa Elena Peninsula, Guanacaste. Distribution outside Costa Rica: From eastern Nicaragua to western Panama (Savage 2002). |
