Urticina eques in a Channel Islands sea bottom rich in marine life. Also seen are a purple sea urchin, a chestnut cowrie, and many strawberry anemones. Urticina eques is dioecious. In California, female ripeness occurs in December as the sea temperature begins to fall.
The sea anemone benefits from the products of the algae's photosynthesis, namely oxygen and food in the form of glycerol, glucose and alanine; the algae in turn are assured a reliable exposure to sunlight and protection from micro-feeders, which the sea anemones actively maintain. The algae also benefit by being protected by the sea anemone's ...

The starlet sea anemone is used as a model organism in research. [34] It is easy to care for in the laboratory and a protocol has been developed which can yield large numbers of embryos on a daily basis. [35] There is a remarkable degree of similarity in the gene sequence conservation and complexity between the sea anemone and vertebrates. [35]
