Tadpoles come from newly hatched frog and toad eggs. New tadpoles have no arms or legs, and most cannot breathe atmospheric oxygen. They also have long tails. As they mature, the tadpoles develop extremities, lose their tails and those born unable to breathe air grow lu...
Tadpoles are aggressive eaters because of their rapid growth rate, and one of their favorite foods is algae that grows in pond water and along rocks. As they develop, tadpoles start to consume many microscopic water bugs, such as amoebae, fleas and rotifer.
Most tadpoles begin metamorphosis in water but emerge onto land as they near adulthood. Two species of frog have terrestrial tadpoles that never enter water during metamorphosis.
The majority of tadpoles are herbivores and should be fed plants, such as spinach or other leafy greens, which seem to be their favorites. These should be chopped up into tiny pieces and frozen to make them easier for the tadpole to eat.
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, id...
Fish have gills because these organs are used to extract oxygen from the surrounding water in which a fish lives. Gills are different from lungs because gills generally work unidirectionally: water moves in one direction across the gills in order for the organs to extra...
Tadpoles breathe through the gills by moving their throat through regular rhythmic movements, known as pulsing. They can also breathe through lungs, according to Natural History. When they metamorphose into frogs, they eventually lose their gills and start breathing thr...
