Turritopsis dohrnii aka "immortal jellyfish"
Immortal jellyfish
The turritopsis dohrnii is a species of jellyfish found in the mediterranean sea.
Taxonomical heirarchy
Kingdom: Animalia
Phylum: Cnidaria
Class: Hydrozoa
Order: Anthoathecatae
Family: Oceanidae
Genus: Turritopsis
Species: Dohrnii
Fun Fact:
Kingdom: Animalia
Has a nucleus
A Little Deeper
Phylum: Cnidaria
Two basic body functions
medusa and the sessile polyp.
Class: Hydrozoa
A class of marine invertebrates. Solitary animals, with tentacles arising from the bell margin.
Order: Anthoathecatae
belonging to the Cnidaria, also always have a polyp stage.
Family: Oceanidae
Contains at least 50 species, one of which the turritopsis are aprt of.
Genus: Turritopsis
It is a hydrozoan whose medusa, or jellyfish.
Also able to revert its cells back to polyo stage, and keep reversing the process.
Species: Dohrnii
Species of small jellyfish.
Skeletal/Muscular System
They have limited control over movement, but can use their hydrostatic skeleton to navigate through contraction-pulsations of the bell-like body.
Digestive System
Immortal Jellyfish are carnivores, which mean they feed on other animals. They drift through the ocean current and trap food as they pass with their tentacles. Their food sources are zooplanktons, eggs, larvae, and crustaceans.
Nervous System
Jellyfish employ a loose network of nerves, located in the epidermis, which is called a "nerve net".
Reproductive System
After an Immortal Jellyfish becomes sexually mature (had sex at least once), then they are able to revert back to their juvenile form, which can go on forever, making them immortal.

Life Cycle
The eggs develop in gonads of female medusae, which are located in the walls of the manubrium (stomach). soon become mature sexually after polp stage and start over.
Interesting facts
The process that lets the turritopsis remain immortal is called transdifferentiation and it involves one cell converting from one type to another. They are 4.5 mm tall and wide.
