Polyps live in many underwater habitats. There are both fresh and salt water species. The most well known polyps are the individual animals that create coral reefs, which are generally found in shallow, tropical seas.
No. They eat tiny, tiny things they filter out of the water.
Constant wave churning and the removal of organic solids by the action of filter feeders like sand worms,clams,mussels and coral polyps.
Lakshadweep is made from tiny marine animals known as polyps. The skeleton of these creature after they die are known as coral. Since Lakshadweep contains many polyps it is known as coral islands
Only salt water not brackish or fresh fresh and brackish water kills the polyps
One of the main differences between plants and animals is that plants make their own food, whereas animals must eat plants or other animals (although there are a few exceptions). They use tentacle-like structures to gather food from the surrounding water. The "branches" of a coral and actually individual animals, called polyps. Amazingly, these polyps actually release the coral's eggs into the water. When baby coral first hatches, resembles a tiny jellyfish (jellyfish are surprisingly in the same phylum as jellyfish: cnidaria), and floats aimlessly until it lands on a rock or seabed. Once it has landed, it creates a protective shell that keeps it anchored in place. Soon, polyps begin to emerge, and the process begins again.This site will give you more detailed info on why coral is considered an animal:http://oceanworld.tamu.edu/students/coral/coral1.htmhope this helped!
Corals Coral reefs are found in shallow water, ranging to depths of 60 m. Some species prefer either cooler temperate water while others are found along tropical reefs, such as the Great Barrier Reef, with waters ranging in temperatures from 18 - 33 °C. Living in colonies: They generally occur in large numbers as colonies of individual polyps linked by tissue. Resources, such as food, are then shared amongst the individuals in the colony. Species: polyps and reef builders. Corals Coral reefs are found in shallow water, ranging to depths of 60 m.

Coral reefs are found in salt water, on the ocean floor. Most often they are found in warm, shallow water.
In theory....no, the hair algae doesnt kill corals, what does kill the coral is hair algae growing profusely next to it preventing the coral extending its polyps and getting sun light. Algae can cover the 'mat' of some species of coral such as xenia and star polyps also preventing the polyps from extending and getting nutrients and sunlight. = = Another possibility is that some conditions that favor algae may not favor the life of the coral such as temperature of the wate and pH of the water.
There is no such thing as a non-living organism.
Coral is at the same temperature as the water it is found in.
The biggest problem facing Coral Reefs is water pollution. The tiny animal that make up the reef, Coral Polyps, are extremely sensitive to changes in their environment. Man-made pollution can caused Coral 'die offs' that wipe out large areas of a reef in a short period of time. "Pollution" factors can include the raising of the water temperature surrounding the reef, as well as chemical pollution. Some sea animals do feed on Coral Polyps, but that effect is minimal and a part of the natural environment.
