Life history

Breeding season

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).

Egg

Females may lay over 1,000 eggs in a single oviposition event (Stebbins and Hendrickson 1959).

Tadpole

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).

Ecology behavior and evolution

Call

Hypsiboas crepitans has a rattle-like call, consisting of a series of short, low or medium pitches notes (Ibanez et al 1999).

Behavior and communication

Males do not construct nests, as do other species in this group (Duellman 2001, Fouquette 1966).
