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]
Once the eggs hatch, the adult piggybacks the tadpoles, one at a time, to suitable water: either a pool, or the water gathered in the throat of bromeliads or other plants. The tadpoles remain there until they metamorphose, in some species fed by unfertilized eggs laid at regular intervals by the mother. [9]
The eggs hatch and the tadpoles take 30 to 55 days to develop before undergoing metamorphosis into juvenile toads about 1 cm (0.4 in) long. The tadpoles feed on algae which they scrape from underwater vegetation. Adults are carnivorous and feed on any small invertebrates they can find. [6]
