What does word anthozoa mean?

What makes a anthozoa?
The Class Anthozoa includes a variety of animals that have polyps with a flower-like appearance. In these forms, the gastrovascular cavity is large. It is divided by walls or septa, which arise as folds from the body wall.
Why is the anthozoa class the most important?
Anthozoans are found around reefs and shallow waters. Since they help build coral reefs they have been valuable to scientists in learning about the past climates of certain regions.

What are two characteristics of the class anthozoa that distinguish it from other cnidarian classes?
The class Anthozoa includes all cnidarians that exhibit a polyp body plan only; in other words, there is no medusa stage within their life cycle. Examples include sea anemones (Figure 1), sea pens, and corals, with an estimated number of 6,100 described species.
Where can anthozoa be found?
Anthozoans are found from intertidal zones to deep ocean trenches, in both warm and cold waters. Reef-building corals are only found in shallow tropical and subtropical waters. Anthozoa are found in the largest numbers in warm, tropical waters in coral reef habitats.
What are the characteristics of Cubozoa?
The most obvious characteristic of cubozoans is the box-like shape of their bell. The manubrium and mouth are located inside the bell, and the velarium is along the edge of the bell. Pedalia are muscular extensions of the bell and the tentacles are attached to the pedalium.
