Life History, Abundance, Activity, and Special Behaviors
The species is arboreal
and nocturnal, and is found in primary
and secondary forests, usually on
trunks and branches. Males call, often
in groups, from low vegetation or
immersed in small water bodies.
Reproduction occurs throughout the
year, after heavy rain, but most
frequently at the start of the rainy
season. The clutches contain about
2000 black eggs that are deposited as a
film on the surface of temporary ponds.
The tadpoles are voracious predators of
eggs of their own and other species,
oophagus differ by having a single vocal
sac, and smaller size. Some individuals
of O. oophagus also have numerous
white spots on the sides of the body.
