Stalked Jellyfish
Légende
Stauromedusae are the stalked jellyfishes, of the class Staurozoa within the phylum Cnidaria. They are unique in that they do not have an alternation of polyp and medusa life cycle phases, but are interpreted as an attached medusa stage, with a life style more resembling that of polypoid forms. They have a generally trumpet-shaped body, positioned upside-down in comparison with other jellyfish, with the tentacles projecting upwards, and the stalk located in the centre of the umbrella. Ernst Heinrich Philipp August Haeckel (16 February 1834 – 9 August 1919) was a German biologist, naturalist, philosopher, physician, professor, marine biologist, and artist who discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms, and coined many terms in biology..
