The Yellow Cluster Anemone (Parazoanthus axinellae) is a marine (saltwater) zoanthid coral in the Parazoanthidae family. It is also known as the Sea Mimosa. It is an animal, not a plant.
The Yellow Cluster Anemone is yellow or orange. It is a cluster of individual polyps connected by a tissue called coenenchyme. Each polyp has 24-36 tentacles in two whorls. The polyps retract into their tube when threatened.
The polyps measure less than 1 centimetre (less than 1 inch) in height.
It is found in the tropical waters of the southern Atlantic Ocean of Europe and in the Mediterranean Sea. It likes rocky sea beds.
It is active both day and night.
It forms colonies quite quickly. Colonies live close together.
