Yellow cluster anemone (Parazoanthus axinellae Schmidt, 1862) is a zoanthid coral found on the southern Atlantic coasts of Europe and in the Mediterranean Sea. Zoanthids differ from true sea anemones, in having a different internal anatomy and in forming true colonies in which the individual animals (polyps) are connected by a common tissue, called the coenenchyme Phylum Cnidaria, Classe Anthozoa.

The species is yellow or orange in colour and each polyp has twenty-four to thirty-six tentacles disposed in two whorls. The polyps are 5 millimetres (0.20 in) in diameter and 20 millimetres (0.79 in) in height. They are connected together in small colonies by a continuous layer of tissue, the coenenchyme. In this species there are sometimes thick yellow spongy masses of tissue at the base of each zooid. A similar zooanthid is Parazoanthus anguicomus, but that species has more numerous tentacles.

  Distribution and habitat Parazoanthus axinellae is found in the temperate eastern Atlantic Ocean and the Mediterranean Sea. It occurs at depths between 23 and 45 metres (75 and 148 ft) on rocky substrates.
