Rocky intertidal communities
________ are made up of zonations.
Mobile organisms
________ can move to the non- wave exposed side of a rock.
Mesenterial filaments
________= strings that come off individual members to reel in food, think of them as "long fishing nets.
Corals
________ are basically just copies of the first polyp that landed there.
surface area
Gathering in numbers= increasing the ________ so that the wave goes over the entire group, decreasing the force of the wave.
Radiator effect
Increased surface area on their bodies
thin bones
Reduced skeletons= ________ that make up their skeleton.
Tritons
The only ones that can consume them because the sea star is poisonous.
bioluminescence
the use of chemical reactions in body to make light.
Endoparasites
internal parasites (muscles, guts, blood)
Operculum
Covering thats used to close their bodies from the external environment.
Transport host
only used to move from one organism to another.
Intertidal
"between communities"
Operculum
Covering thats used to close their bodies from the external environment
Hermatypic corals
"reef-building corals", mutualistic relationship with zooxanthallae
Ahermatypic corals
"non-reef building corals", lives in deep water
Fringing Reef
Close to the shore, the youngest type of reef
Barrier Reef
Further away from the coast, very large
Atoll
The oldest type of reef
Patch reef
small, isolated reefs that grow up from the open bottom of the island platform or continental shelf
Planula
Free-floating microscopic Cnidarians
What creates the foundation for a coral reef?
Coraline red algae dies and releases calcium that is mixed with sand
Photic zones
Areas that can receive pockets of sunlight
How can mobile organisms mitigate the effects of wave shock?
By moving to a non-wave exposed side of a rock
How can non-mobile organisms mitigate the effects of wave shock?
Evolved to have thicker shells (“adhesives”), lowering their profile, and gathering in numbers
Most organisms living in coral reefs are
Euryhaline
