Tadpole
Description
A tadpole is the wholly aquatic larval stage in the life cycle of an amphibian, particularly of a frog or toad. During the tadpole stage of the amphibian life cycle, most respire by means of autonomous external or internal gills. They do not usually have arms or legs until the transition to adulthood, and typically have dorsal or fin-like appendages and a tail with which they swim similar to most fishes. Most tadpoles are herbivorous, subsisting on algae and plants.
