What is the lifespan of a jellyfish?
Most jellyfish are short lived. Medusa or adult jellyfish typically live for a few months, depending on the species, although some species can live for 2-3 years in captivity. Polyps can live and reproduce asexually for several years, or even decades. One jellyfish species is almost immortal.
