What is a pollywog?

A:

A pollywog is another name for a tadpole, or the larval stage in the life cycle of an amphibian, namely frogs and toads. While most tadpoles are aquatic and spend most all their time in the water, a few are terrestrial.

Full Answer

Pollywogs breathe by means of outward or inward gills and feed mainly on plants and algae. As the young amphibians mature, they gradually grow arms and legs, outwardly absorbing their tail by apoptosis. Around the same time, pollywogs begin developing lungs and are commonly found near the surface of the water breathing air as they make the transition to adulthood.

  • Q:

    How do you identify a tadpole?

    A:

    A tadpole can be identified by the length of the body, the length and shape of the dorsal tail fin and the ventral tail fin, the tail musculature, and the placement of the eyes and nostrils. The tadpole's habitat and the time of year it's found are also clues. Still, identifying tadpoles remains difficult because tadpoles are small and are in a constant state of metamorphosis.
