Emerald-eyed tree frog

Species description based on Ibanez et al. (1999) and Duellman (2001). A large treefrog with long, slender arms and legs (males to 59 mm, females to 68 mm). Males have a dagger-like spine at the base of the thumb.

The dorsal surface is pinkish tan with some darker brown spots, blotches or other markings. A thin, dark middorsal stripe is usually present. Dark bars are present on the upper surfaces of the thighs, and extend onto the rear surfaces of the thighs.

The concealed surfaces are colored similarly to the dorsum, except for the dark barring on the rear surfaces of the thighs.

The eye is grey, with a bronzy or yellowish cast.

The webbing between the hands and feet is not particularly extensive in Hypsiboas crepitans. The webbing is pale in coloration.

Breeding occurs throughout much of the rainy season (Ibanez et al. 1999, Duellman 2001). Males call from the edges of temporary ponds or flooded grassy areas (Ibanez et al. 1999).

Females may lay over 1,000 eggs in a single oviposition event.[3]

Tadpoles are grey or light brown (Duellman 2001). The tail has more yellow undertones (Duellman 2001). The tadpole body is ovoid, with a rather long tail that ends in a distinct point (Duellman 2001). The upper caudal fin is much deeper than the lower (Duellman 2001).
