Are all jellyfish life cycles the same?
Jellyfish have a complex life cycle that includes both sexual and asexual stages, and in most cases Medusa is the sexual stage. Sperm fertilize an egg, grow into a larval planula, become a polyp, germinate into an efirae, and then transform into an adult medusa. For some species, certain steps may be skipped.
How long do jellyfish live?
Most jellyfish can live for less than a year, and some of the smallest jellyfish can only live for a few days. Each type has a natural life cycle in which the morphology of the jellyfish is only part of the life cycle (see video clips showing the different life cycle stages).
How long does it take for a jellyfish to become an adult?
