Tadpole - Wikipedia
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.

2021年5月26日 · Frog Tadpole Stage. Tadpoles or Polliwogs are the aquatic larval stage of frogs that evolved from eggs after 3 to 25 days. They measure about 40-45mm and live in water. Tadpoles evolve for 14 to 16 weeks depending on the species and the climate in which they live. Once frog eggs have hatched, they will turn into tadpoles.

Tadpole | Definition, Gills, & Facts | Britannica
tadpole, aquatic larval stage of frogs and toads. Compared with the larvae of salamanders, tadpoles have short oval bodies with broad tails, small mouths, and no external gills. The internal gills are concealed by a covering known as an operculum. Tadpoles undergo a visually striking metamorphosis before they achieve adulthood.
Understanding the Heart and Anatomy of a 4mm Tadpole
The major parts of the heart at the 4mm stage are the endocardium, myocardium, and pericardium. The pericardium will rise from the surrounding mesodermal membrane. A thicker mass of mesoderm within the pericardium is the myocardium.
