It is one of the few known cases of animals capable of reverting completely to a sexually immature, colonial stage after having reached sexual maturity as a solitary individual.
The taxonomy of the Cyanea species is not fully agreed upon; some zoologists have suggested that all species within the genus should be treated as one. Two distinct taxa, however, occur together in at least the eastern North Atlantic, with the blue jellyfish (Cyanea lamarckii Péron & Lesueur, 1810) differing in color (blue, not red) and smaller size (10–20 cm [3 + 7 ⁄ 8 – 7 + 7 ⁄ 8 ...
Scientists in Spain have unlocked the genetic code of the immortal jellyfish - a creature capable of repeatedly reverting into a juvenile state - in hopes of unearthing the secret to their unique ...
Aurelia aurita (also called the common jellyfish, moon jellyfish, moon jelly or saucer jelly) is a species of the family Ulmaridae. [ 1 ] [ 2 ] All species in the genus are very similar, and it is difficult to identify Aurelia medusae without genetic sampling; [ 3 ] most of what follows applies equally to all species of the genus.
Meanwhile, a species of jellyfish may have already figured out. The Turritopsis dohrnii is believed to be the only creature in existence capable of continuous 'Immortal' jellyfish roams Earth's oceans
According to the World Register of Marine Species, this genus includes the following species: [ 2] Turritopsis chevalense (Thorneley, 1904) – species inquirenda. Turritopsis dohrnii ( Weismann, 1883) also known as the " Benjamin Button jellyfish", or the "immortal jellyfish". It can reverse its life cycle and transform itself back to a polyp ...
