: Includes soft corals, sea pens, and sea fans. They strictly possess eight branched (pinnate) tentacles and eight mesenteries. Ecological Importance
: Unlike many other cnidarians (such as jellyfish), Actinozoans do not have a medusa (free-swimming) stage in their life cycle. They remain as polyps throughout their lives. actinozoa
The name Actinozoa stems from the Greek words aktis (ray) and zoon (animal), referring to their radial symmetry and the "ray-like" appearance of their tentacles. : Includes soft corals, sea pens, and sea fans
Actinozoans are the primary architects of , which are among the most biodiverse ecosystems on Earth. Stony corals secrete calcium carbonate skeletons that form the structural foundation of these reefs, providing habitat for thousands of other marine species. They remain as polyps throughout their lives
: Includes sea anemones and stony corals. They typically have tentacles and mesenteries in multiples of six.
: While sea anemones are typically solitary, many Actinozoans (like reef-building corals) form massive colonies of interconnected clones. Classification
: They use tentacles armed with specialized stinging cells called nematocysts to capture prey, ranging from plankton to small fish.
