es. ''A. trivittata'' is diurnal and terrestrial. Its distinctive features include its large size (up to 50 mm), granular skin, lack of webbing between digits, and distinctive striped markings. The colour of these markings varies; typically the stripes are green, but yellow and orange specimens occur, as well. It lays terrestrial eggs, which are hidden in clutches under leaves. The males take care of the eggs and carry the tadpoles on their backs to pools once they have hatched. It is threatened by

Description

The male three-striped poison frog has a

of about and the female reaches about . It has a slightly protruding snout with no teeth, finely granulated skin on its dorsal surface and smooth skin on its flanks and ventral surface. The digits are unwebbed and the first finger is longer than the second finger. The colouring of this species varies somewhat between locations but in general it has a black back and sides, a black belly suffused blue posteriorly and yellowish-green or light-brown limbs. Two yellowish-green lateral stripes run from the snout to the hind legs.


Biology

The three-striped poison frog is a diurnal, terrestrial species that is found among the leaf litter of the forest floor in both primary and secondary tropical forests. The main food of this frog is

s which are plentiful on the forest floor. Males are territorial during the breeding season but females are not. The eggs are laid in small clutches underneath fallen leaves during the rainy season. They take about 15 days to hatch during which time the male guards them. He then carries them to a suitable ephemeral pool or water-filled crevice where the tadpoles develop for from 41 to 54 days before undergoing
metamorphosis Metamorphosis is a biological process by which an animal physically develops including birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. Some inse ...
