Linckia laevigata is characterized by five cylindrical arms with a bright blue or light blue body color and yellow tube feet. Green, pink, and yellow colors have also been observed. Individuals can grow up to 30 to 40 centimeters across. These animals get their color from a blue pigment called linckiacyanin and some accessory yellow carotenoids. The starfish colors vary, depending on the exact ratio and combination of pigments in each individual.
