Question

What are corals? give me a little answer​

Answer 1

Answer:

$Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically live in compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton.}$

Answer 2

Answer:

When corals are mentioned, most people think about clear, warm tropical seas and reefs filled with colorful fish. In fact, stony, shallow-water corals — the kind that build reefs — are only one type of coral. There are also soft corals and deep water corals that live in dark cold waters.
