Cnidaria. General Information  Eumetazoans  (true animals) all animals other than sponges-have both tissues and symmetry  When eumetazoans develop-they.

The ImmortalJellyfish Turritopsis nutricula By: Meghan Steere Ula means small one

Contents Habitat Taxonomy Feeding Behavior Life Span Human Impact

Habitat Temperate to tropical regions Originated in Pacific Size 4-5 mm long (.2 in.) In all the oceans Probably the Caribbean Size is in the Medusa stage Has about 8 tentacles as a young medusa, 80-90 as an adult.

Taxonomy & Description Kingdom-Animalia Phylum-Cnidaria Class-Hydrozoa Order-Anthoathecata Family-Oceaniidae Genus-Turritopsis Species-nutricula All colonial hydrozoans also include some polyps specialized for reproduction Order: solitary animals, always have a polyp stage

Feeding Behavior What it eats: What eats it: Brine Shrimp Fish eggs Microscopic Plankton Small crustaceans What eats it: Turtles Fish Motors Planktons such as Phytoplankton and zooplankton Small crustaceans such as: krill, larvas

Life Span Biological Immortality Reproduction Transdifferentiation Unknown Asexual Transdifferentiation= ontogeny reversal Reproduction assumed to be males fertilize spawned mature eggs Then mother lays eggs and leaves them to hatch

Life Span cont. Experiments EP= epidermis Cell types: Bell surface, circulatory canal system, gastrovacular. EP= epidermis OM = outer mesogloea EN = endoderm IM = inner mesogloea SM = striated muscle GC = gastral cavity RC = radial canals RIC = ring canal T = tentacle In the scientific article I read, experiments were done to locate what was necessary for transdifferentiating what is particular about these cells – and what exactly is required of them – remains unclear

Human Impact Boats Discharged ballast water Responsible for distribution and death
