3. 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, as an adult.

4. 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

5. 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

6. 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

7. 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

8. Human Impact Boats Discharged ballast water
Responsible for distribution and death
