Turritopsis dohrnii
Taxonomic Group: Cnidarians-Hydrozoans
Common name: IMMORTAL JELLYFISH

Overview:

The immortal jellyfish (Turritopsis dohrnii) has both a polyp and medusa stage, and can switch between the two stages. This ability to go from medusa to polyp means an individual can live a very long life! It was first described from Naples, Italy, and is a common hydroid on rocky substrates in the Western Mediterranean and Adriatic where its distribution is considered cryptogenic. Introduced populations are known from the Indian River Lagoon, Florida; both the Caribbean and Pacific coasts of Panama; and Japan. The hydroid stage of this species can be found attached to rocks, docks, pilings and ships’ hulls. No impacts have been reported from introduced populations.
