Abstract Siderastrea radians (Pallas) is a common West Indian reef coral that displays wide morphological variation. The hypothesis that a spherical form of free living colonies of S. radians has advantages for survival was examined in Barbados. Colonies were sampled from tide pools and from random quadrats at four reef flat sites subjected to strong wave action. Survival was found to be a positive function of colony size measured as living surface area and was correlated with stage of development toward a spherical shape. The combination of spherical shape and larger size confer a selective advantage on free living colonies in disturbed habitats.
