- Explain how comb jellies are able to swim through the water.
It uses 100’s of cilia at the same time to swim through the water.
Explain exactly why fire corals are called “The Immortal Jellyfish.”

Detail the process that sponges use to filter feed.
Pores on the outside of the sponge take in water, filter out their food and release the waste from the top.
How do anemone and coral polyps feed on prey?
They use stingers to paralyze the prey and the tentacles move the food to their mouth.
What two methods do sponges use to protect themselves from predators?

What is Coral Bleaching? What effect does it have on the World Ocean?
It is a stress response from environmental changes. The effect is dangerous to the World Ocean. Since Coral is the habitat to so many different organisms, if it dies, the organisms living there have to either move or they will die if they can’t adapt.
