A tadpole 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.
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

Tadpoles are frog larvae, in the same way that caterpillars are butterfly larvae! For the first week or two after hatching, tadpoles won’t move around very much, as they’re still absorbing some nutrition from the yolk of their egg. However, once the yolk is all gone, the tadpoles are big and strong enough to venture out into their watery world!
Tadpoles often have horny beaks. Their gills are internal and covered by an operculum. Water taken in through the mouth passes over the gills and is expelled through one or more spiracular openings on the side of an opercular chamber. Anuran larvae are microphagous and thus feed largely on bacteria and algae that coat aquatic plants and debris.
27 de dic. de 2023 · Tadpoles Are Baby Frogs. Tadpoles are the larval stages of frogs and toads. Amphibians differ from most other vertebrates (higher organisms with a backbone) in that their eggs develop into a larval stage, known as a tadpole. The word comes from the old English words for a toad and a head (poll).
