Freshly hatched tadpoles had a prominent yolk sac, the contents of which were rapidly used up during the first few days of development.
They multiply enormously in the crop, undergoing a great change in appearance, being tadpole-like in form and having a crithidia-like arrangement of the nuclei.
This would imply indiscriminate use of available niche space by tadpoles, with no other factor limiting their distribution.
Pond tadpoles with generalized morphology: is it time to reconsider their functional roles in aquatic communities?
In this situation, oncomiracidia are available to infect tadpoles during the brief period of the rainy season.
Eggs and tadpoles were reared to metamorphosis in buckets of stream water to confirm species identification.
Most ascidian species exhibit indirect development in which the egg develops into a tadpole larva.
Tadpoles were counted and the number of tadpoles per sweep calculated.
