WebAnimals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle .

WebFish eggs cannot swim at all, and are unambiguously planktonic. Early stage larvae swim poorly, but later stage larvae swim better and cease to be planktonic as they grow into juveniles. Fish larvae are part of the zooplankton that eat smaller plankton, while fish eggs carry their own food supply.
