In captivity, tadpoles have been raised on a variety of diets, ranging from algae to the eggs of other dart frogs, but with minimal success. O. pumilio tadpoles are considered obligate egg feeders, as they are unable to accept any other form of nutrition. After about a month, the tadpole will metamorphose into a small froglet.
A tadpole or polliwog (also spelled pollywog) is the larval stage in the biological life cycle of an amphibian. Most tadpoles are fully aquatic, though some species of amphibians have tadpoles that are terrestrial. Tadpoles have some fish-like features that may not be found in adult amphibians such as a lateral line, gills and swimming tails.
The life cycle is short. The tadpole-shaped larva usually performs the tail shift less than one day after fecundation, becoming fully functional juveniles. Adults usually reproduce after 5 to 7 days depending on the species. [11] Fertilisation is external. The body wall ruptures during egg release, killing the animal. [30]
Its coloring is usually brown but can be red, gray, or black. ... The eggs hatch and the tadpoles take 30 to 55 days to develop before undergoing metamorphosis into ...
During the final stages of transformation when the tadpoles have four limbs and a tail, they stop feeding for a short time while their mouths widen and their digestive systems adjust from herbivorous to carnivorous. Pacific tree frogs mature quickly, and usually mate the season after metamorphosis. They can live up to eight years in captivity.
The eggs and tadpoles can be preyed upon by fish, which is why these frogs prefer ephemeral ponds and wetlands to breed and lay their eggs Their dark markings and tendency for body coloring to vary depending on their habitat allows them a layer of camouflage as a defense tactic.
Tadpoles have distinctive mouth morphology, of having black keratinized hooks. [14] Tadpoles have elliptical bodies, with compressed and long tails, and dark brown coloring besides sometimes apparent lack of pigmentation on tail fins. [15] Tadpole eyes are black with iris colored with gold specks. [15]
