What coral is used for medicine?
The pharmaceutical industry has found corals provide value in the development of new products. Certain corals, for example, stimulate the welding of broken bones. Components of a Caribbean sponge allow for the creation of Zidovudina, a medicine used to treat HIV.
What is difference between coral and polyp?
There are also soft corals and deep water corals that live in dark cold waters. Almost all corals are colonial organisms. This means that they are composed of hundreds to hundreds of thousands of individual animals, called polyps.

What is the relationship between coral and polyps?

Do corals have gender?
Most corals are hermaphrodites as they produce both male and female reproductive cells (known as gametes). Corals can reproduce in many ways: Spawning involves eggs and sperm being released into the water column simultaneously.
How fast do corals grow?
With growth rates of 0.3 to 2 centimeters per year for massive corals, and up to 10 centimeters per year for branching corals, it can take up to 10,000 years for a coral reef to form from a group of larvae. Depending on their size, barrier reefs and atolls can take from 100,000 to 30,000,000 years to fully form.
How long does coral spawning last?
The spawning lasts between a few days and a week. This is because different species release their eggs and sperm on different days to prevent hybrids from being produced. The phenomenon — which only happens at night — resembles an underwater snowstorm.
