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.
Each is a member of one of three monophylitic clades. All tunicate larvae have the standard chordate features, including long, tadpole-like tails. Their larva also have rudimentary brains, light sensors and tilt sensors. [28] The smallest of the three groups of tunicates is the Appendicularia. They retain tadpole-like shapes and active swimming ...
As a generalized system, Gosner stages may not be adequate for describing development of some anuran tadpoles. [3] For example, in the torrent-dwelling tadpoles of Ansonia longidigita and Meristogenys orphnocnemis , the usual Gosner stages become inappropriate beyond the stage 41 because the tadpoles retain their oral disc longer than the ...
Triops cancriformis, European tadpole shrimp or tadpole shrimp is a species of tadpole shrimp found in Europe to the Middle East and India. [2]Due to habitat destruction, many populations have recently been lost across its European range, so, the species is considered endangered in the United Kingdom and in several European countries.

In the mathematical discipline of graph theory, the (m,n)-tadpole graph is a special type of graph consisting of a cycle graph on m (at least 3) vertices and a path graph on n vertices, connected with a bridge.
The tadpole madtom is an invertivore, planktivore, but also feeds on particulate. A Common food source for the tadpole madtom are immature insects and small crustaceans such as cladocera, ostracods, hyalella, and chironomids. Another popular food source is small crustaceans such as amphipods and isopods. Smaller fish feed more on small ...
