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 order Notostraca, containing the single family Triopsidae, is a group of crustaceans known as tadpole shrimp [1] or shield shrimp. [2] The two genera, Triops and Lepidurus , are considered living fossils , with similar forms having existed since the end of the Devonian , around 360 million years ago.
Indirana semipalmata tadpole,on a plastic sheet used to cover a shed from, Hosamata, Puttur, Karnataka, India Tadpole from Coorg, India on tree bark. The ecology and biology of Indirana semipalmata has not been extensively studied. It is a terrestrial species generally found on vegetation beside the banks of streams and rivers (riparian habitats).

Tadpoles probably spend most of their time attached to such substrates by a large oral sucker. The large, sucker-like mouth parts of the tadpoles are a second distinctive feature of the species, enabling survival in turbulent water unsuitable for other frogs. They prefer turbulent water to smooth, swiftly flowing water. [16]
Adults hunt in spring and summer, but only at night or during light rains. Spadefoot tadpoles are dimorphic. Within a cohort, some tadpoles have large mouthparts, while others have much smaller mouthparts. As well as consuming other types of food, large-mouthed individuals are cannibalistic, swallowing other tadpoles whole. [4] [10]
Triops is a genus of small crustaceans in the order Notostraca (tadpole shrimp). The long-lasting resting eggs of several species of Triops are commonly sold in kits as pets. The animals hatch upon contact with fresh water. Most adult-stage Triops have a life expectancy of up to 90 days and can tolerate a pH range of 6 to 10. In nature, they ...
The tadpole of this species is considered unpalatable to many species that would commonly predate on tadpoles. They also exhibit behaviors to avoid predation. To avoid fish, the tadpoles will move to stream margins in order to make them inaccessible to the fish. The tadpoles will also reduce activity after sensing a fish's chemical cues. [21]
