How old can a jelly fish live up to be?

Answer 1

Technically, most small jellyfish live to be 12-15 years old. Some larger jellyfish can live to be twice that age! In case you didn't know, jellyfish can be quite fatal! So while you're on the shoreline watch out, because sometimes jellyfish can wash up on the shore. Also, watch your step, because jellyfish can get spooked by whoever goes near them!

Answer 2

Jellyfish lifespans typically range from a few hours (in the case of some very small hydromedusae) to several months. The life span and maximum size of each species is unique. One unusual species is reported to live as long as 30 years and another species, Turritopsis dohrnii as T. nutricula, is said to be effectively immortal because of its ability to transform between medusa and polyp, thereby escaping death. Most of the large coastal jellyfish live about 2 to 6 months, during which they grow from a millimeter or two to many centimeters in diameter.
