Turritopsis dohrnii aka "immortal jellyfish"
Transcript of Turritopsis dohrnii aka "immortal jellyfish"
The turritopsis dohrnii is a species of jellyfish found in the mediterranean sea.
Has a nucleus
A Little Deeper
Two basic body functions
medusa and the sessile polyp.
A class of marine invertebrates. Solitary animals, with tentacles arising from the bell margin.
belonging to the Cnidaria, also always have a polyp stage.
Contains at least 50 species, one of which the turritopsis are aprt of.
It is a hydrozoan whose medusa, or jellyfish.
Also able to revert its cells back to polyo stage, and keep reversing the process.
Species of small jellyfish.
They have limited control over movement, but can use their hydrostatic skeleton to navigate through contraction-pulsations of the bell-like body.
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.
Jellyfish employ a loose network of nerves, located in the epidermis, which is called a "nerve net".
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.
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.
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.
