Turritopsis dohrnii, the immortal jellyfish has turned up in the marina. This awesome little critter is capable of reverting to a sexually immature colonial stage after having reached sexual maturity as a solitary individual. Theoretically this process can go on indefinitely, effectively rendering the jellyfish biologically immortal. Because of their small size Turritopsis is thought to be spreading unnoticed around the world through ballast water of ships. #ecotourism #bayofplenty #newzealand #
