what makes water move in sponge
flagellum of colar cells
what type of phylum is knideria under
animal kingdom
whats are the three top divsions in animals
kingdom phylum class
what are the three classes under cnideria
hydrozoan, scyphozoa, anthazoa
in life cycle what is dominant in hydrozoan
Polyp then medusa
what is dominant in scyphozoa life cycle
medusa, then breif polyp
whats unique about anthazoa life cycle
it doesnt have medusas just polyp
what are some examples of anthazoa
coral,sea anemone, sea fan
why are cnidaria called cnidaria
because they have cnidoblasts
how do hydrozoan get food
with their stinging cells
what are cnidoblasts
the stinging cells
what are the platyhelminthes 3 groups
turbellaria, trematoda, and cestoda
which are the flatworms called phylum name
platyhelminthes
life cycle of blood fluke
1.larvae drills into persons foot
2.adults in intestines
3.adult produce egg
4. eggs go out with fecal material
5.then they go into snail
6. then new larvae is released and they look for more humans
is human a primary or secondary host for blood flukes
primary cus thats where adult is
where does blood fluke adult live
in the intestines of humans
what is the secondary host
snail
