How do coral polyps obtain food and digest it?
There are three types of nematocysts:
- Glutinant: nematocyst has a sticky surface that is used to stick to prey.
- Penetrant: nematocyst has a harpoon-like structure that is used to penetrate the exoskeleton (hard outer covering) of prey.
- Volvent: nematocyst has a lasso-like thread that is used to wrap itself around its prey.
What lives in coral polyps?
Tiny plant cells called zooxanthellae live within most types of coral polyps. They help the coral survive by providing it with food resulting from photosynthesis. In turn, the coral polyps provide the cells with a protected environment and the nutrients they need to carry out photosynthesis.

What do coral polyps eat?
As a result, they tend to feed on dissolved organic matter which can consist of waste and remnant molecules and cells resulting from larger organisms. Corals also take up a significant amount of inorganic matter, which they use primarily for producing their calcium carbonate skeletons. Calcium, iron, iodine, magnesium, phosphorus and potassium are just a few of the elements they tend to pick up. By studying the efficient way in which the polyps use these elements, scientists have found out a great deal to answer the question “how do coral polyps eat?”
Why do coral polyps come out at night?
Coral polyps are known to come out at night to feed. Their feeding process allows them to eat virtually any tiny organisms or food particles that happen to drift by taken by the water current. Leaving their skeletons, they unfold their tentacles to capture unsuspecting prey by stinging and immobilizing it – in most cases, zooplankton. While most of the carbon energy derived by coral polyps is obtained from their symbiosis with zooxanthellae algae, the need for organic feeding arises from the fact that the zooxanthellae are not capable to provide corals with enough phosphorus and organic nitrogen to keep their tissues properly nourished. As a result, feeding and digestion takes over, ensuring that the polyp has everything it needs to remain healthy.

Coral polyps are small, soft-bodied organisms that are related to jellyfish and sea anemones. They have a hard, protective limestone skeleton called a calicle at their base, which forms the structure of a coral reef. Reefs start when a polyp connects itself to a rock on the sea flooring, then divides, or buds, into countless clones.
Where do coral polyps live?
Corals polyps reside in tropical waters throughout the world, normally near to the surface where the sun’s rays can reach the algae. While corals get the majority of their nutrients from the by-products of the algae’s photosynthesis, they likewise have barbed, poisonous tentacles they can protrude, normally during the night, to get zooplankton and even little fish.
How to feed soft corals?
