The sexes are separate in some sea anemones, while others have individuals with both types of gonads. In some sea anemones, asexual reproduction occurs when pieces of the base are lost during locomotion and these regenerate into new individuals. The method is called a. acontia regeneration. Anthozoa , which are able to grow much faster than other anthozoans because they have a mutualistic relationship with a. coral reef fishes. The members of phylum Ctenophora move about by means of a. fin flexing.
All ctenophores bear both an ovary and a testis.
When a taxon such as a class contains members who have different origins, then the taxon is called a. mutualistic. Sometimes anthozoans will have a mutualistic relationship with green algae to enhance their potential for growth. These algae are a. zoochlorellae. A life cycle that has two different body forms is called a. anthroploid. Tentacular bulb 38.
