Coral cannot move on its own, but the cells inside coral can move around. Coral gets nutrition both by eating small animals using stinging cells on its tentacles and through photosynthetic algae called zooxanthellae that live inside coral tissues and provide up to 90% of coral's energy. Coral can reproduce both asexually through budding where pieces break off and grow into new coral, and sexually when coral spawn gametes around a full moon. Threats to coral include disease, pollution, cyanide and dynamite fishing.

Coral can move?
No, coral itself cannot move, but that’s not the type of transportation we’re
talking about. Actually, it’s the cells inside of the Coral that moves around. Corals have simple
body systems and are a few cells thick. The tissues in their bodies are what helps them with
feeding and movement.
How does it get nutrition?

Reproduction

Asexual or sexual?
truelovecoral.com
Coral is
asexual. Little
pieces breaks
off and the
pieces grows
bigger. Then the same thing
happens. Over and over
again. This process is called
budding. Coral can also be
sexual. This is because they
spawn with the same type of
species, which then release
gametes around a full moon.
General Structure
Coral have simple body systems. A body wall surrounds an
internal space called a gastrovascular cavity. On the inside of
the gastrovascular cavity is the inner lining called a gastroderm.
This is is where digestion takes place.

Respiration
After Coral eats the food is
transported through the body by diffusion.
Diffusion is the process by which molecules
spread from areas of high concentration, to
areas of low concentration. On the food
chain, Coral is a secondary consumer.
Regulation
Coral helps keep the carbon dioxide levels
down.
Also, in the group jelly fish are the odd
ones out because they are the only
cnidarians that can move around. All
cnidarians have bilateral symmetry.
Endangered or Extinct?
Coral is endangered. We are eliminating them by cyanide fishing, and
all of our pollution. Also, coral population is decreasing because of
diseases. Coral is important though. We get our food from the oceans.
But the stuff we get feed off of coral. If coral dies out then our food from
the ocean will too.
