Amazon Milk Frog
These frogs are light grayish in color with brown or black banding. Juveniles show stronger contrast which fades somewhat with maturity. Skin also becomes somewhat bumpy as they age. They are 2.5 to 4 inches in length. Males are smaller than females.
GEOGRAPHICAL RANGE AND HABITAT:
Above or near slow-moving water in humid rainforest regions in northern South America (Colombia, Bolivia, Brazil, Ecuador, Peru and Venezuela.)
Carnivorous. Insects and other small arthropods.
LIFE CYCLE/SOCIAL STRUCTURE:
Nocturnal and arboreal. During the day they sleep in the vegetation near the streams. Reproduction usually takes place during the rainy season (November through May). Males are territorial about their calling sites and physical confrontations may take place. Reproductive strategy which works for them is as follows: The male stakes out a water-filled hollow in a tree or bromeliad. He calls a female who comes and lays a clutch of about 2000 eggs which he fertilizes. He watches over these eggs and calls another female to come. He does not fertilize these eggs but leaves them as food for the tadpoles which hatch from the first eggs. Tadpoles hatch in one day and metamorphosis from tadpole to juvenile takes approximately three weeks. (This development is much faster than most frogs.)
They have large toe pads for climbing. Trachycephalus refers to the elongated snout which is useful for pushing aside leaves and branches and allowing this nocturnal frog to tuck itself into tight hiding places during the day.
Also known as Mission Golden-eyed Tree Frogs or Blue Milk Frogs. The name "Milk Frog" refers to the poisonous, white secretion this frog may secrete when threatened.
Several can be found in the RAD Room in the Wayne and Gladys Valley Children's Zoo.
STATUS IN WILD:
Assessed in 2004 as not significantly threatened at this time, but loss of habitat due to agriculture and logging could be a problem. Listed as a species of Least Concern by the IUCN.
