Tadpole \Tad"pole`\, n. [OE. tadde toad (AS. t[=a]die, t[=a]dige) + poll; properly, a toad that is or seems all head. See Toad, and Poll.]

  1. (Zo["o]l.) The young aquatic larva of any amphibian. In this stage it breathes by means of external or internal gills, is at first destitute of legs, and has a finlike tail. Called also polliwig, polliwog, porwiggle, or purwiggy.

  2. (Zo["o]l.) The hooded merganser. [Local, U. S.]

Douglas Harper's Etymology Dictionary

mid-15c., from tadde "toad" (see toad) + pol "head" (see poll (n.)).


n. 1 A young toad or frog in its larval stage of development that lives in water, has a tail and no legs, and, like a fish, breathes through gills. 2 A type of cargo bike that has two wheels in front and one in back.


n. a larval frog or toad [syn: polliwog, pollywog]


A tadpole (also called a pollywog) is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial. When first hatched from the egg they have a more or less globular body, a laterally compressed tail and internal or external gills. As they grow they undergo metamorphosis, during which process they grow limbs, develop lungs and reabsorb the tail. Most tadpoles are herbivorous and during metamorphosis the mouth and internal organs are rearranged to prepare for an adult carnivorous lifestyle.

Having no hard parts, it might be expected that fossil tadpoles would not exist. However, traces of biofilms have been preserved and fossil tadpoles have been found dating back to the Miocene. Tadpoles are eaten in some parts of the world and are mentioned in folk tales and used as a symbol in ancient Egyptian numerals.

Tadpole (physics)

In quantum field theory, a tadpole is a one-loop Feynman diagram with one external leg, giving a contribution to a one-point correlation function (i.e., the field's vacuum expectation value). One-loop diagrams with a propagator that connects back to its originating vertex are often also referred as tadpoles. For many massless theories, these graphs vanish in dimensional regularization (by dimensional analysis and the absence of any inherent mass scale in the loop integral).

The physics of tadpoles and the word tadpole was invented by Sidney Coleman. The editor was not satisfied, but he changed his mind once Sidney Coleman proposed spermion or lollypop instead. All words are derived from the shape of the Feynman diagram: a circle with a line interval attached to its external side. Tadpole diagrams, in this sense, first appear in a paper by Coleman and Sheldon Lee Glashow in 1964.
