Adopt an Siderastra Radians
"Lesser Starlet" Coral Species

About this coral species:

Siderastrea radians are either encrusting or grow in small, dimpled hummocks up to 30 centimeters (12 in) across but most colonies are much smaller than this. Occasionally it occurs as small calcareous pebbles that roll around in seagrass meadows or as loose flat discs in shallow rocky places. The corallites are not circular but are triangular or four-sided and deep, with 30 to 40 small ridges called septa.

Life on Zoe:

Siderastra radians or Lesser Starlet coral form small colonies. Our only specimen is hidden between two bars of Zoe. You can recognize it from its deep corallite centers and multiple septas (rays) connected between corallites.

Fun fact: 

Growth rates of the lesser starlet coral are low but, because of its great tolerance to an increase in sediment levels and to elevated temperatures, it is an important species for maintaining and restoring damaged reefs and useful for this purpose if sea temperatures continue to rise.

The sexes are separate in the lesser starlet coral. Each of the twenty-eight ovaries in a female polyp produces a flattened oval egg. Spawning takes place all through the year but may be related to the phase of the moon. Well-developed planula larvae have been found being brooded inside female polyps shortly before the full moon.
