Tadpole
A tadpole is a larval frog, toad, salamander, or newt. In this stage it breathes by means of external or internal gills, is at first lacking legs, and has a finlike tail. As a tadpole matures, it metamorphoses by gradually growing limbs and then (in the case of frogs and toads) absorbing its tail.
Most tadpoles are herbivorous, subsisting on algae. In a few species, some tadpoles turn cannibalistic under harsh conditions and feed on other tadpoles living in the pond.

In physics, a tadpole is a Feynman diagram with one external leg (the name is due to Sidney Coleman) and it encodes a one-point function (correlation function of one field). See tadpole (physics).
