Are called "sea anemones" every coral of the order Actiniaria.
The reef-building coral on the Great Barrier Reef is primarily in the polyp stage. Corals are marine animals that belong to the class Anthozoa, and they exist as polyps, which are small, cylindrical structures that anchor to the sea floor and form colonies. Medusa is the free-swimming stage of some jellyfish and is not associated with coral formation. Therefore, it is the polyp stage that contributes to the growth of coral reefs.

A medusa looks like an umbrella and a polyp any idea!
The two body forms of cnidarians are the polyp and the medusa. Polyps are typically sessile, tube-shaped organisms attached to a substrate, while medusae are free-swimming, umbrella-shaped organisms.
Cnidarians have two main body forms: the medusa form, which is free-swimming and umbrella-shaped, and the polyp form, which is stationary and tube-shaped. Medusae have tentacles around the edge and a central mouth, while polyps have a columnar body with tentacles surrounding a central mouth.

The hard coral polyp makes the coral
A polyp is anchored to substrate, like a rock or piece of coral. Anemones are polyps. They catch food with their tentacles and have the mouth on the upside. A medusa is swimming freely. Jellyfish are medusa stages. They catch food with their trailing tentacles and have the mouth on the downside. You can view polyps as the settled ´plant´ and medusa as the free-floating ´seed´, like in a dandelion. Though they aren´t plants at all, of course.
