The Red Sea Star is of the genus Fromia, has multiple black pores or dots on it surface, and can be found in various shades of red (Red). The tips of the arms may be the same color or a lighter color than the rest of the arm, thus making it different from Fromia Inidca (Red). Sea Stars are marine invertebrates that belong to phylum Echinodermata, class Asteroidea, and are closely related to brittle stars, which make up the class Ophiuroidea (Sea). Sea stars exhibit a superficially radial symmetry, and usually have five or more arms that radiate from an indistinct disk (Sea). They do not have movable skeletons, but instead have a hydraulic water vascular system, that has many projections called tube feet, on the ventral face of the sea star's arms, that function in locomotion and feeding (Sea). Red Sea Stars prefer to live alone, and are difficult to distinguish from their mates (Red). .

             There are a variety of different Red Sea Stars. The Bali Red Star is a miniature sea star that never exceeds three inches, and is found over sandy substrates, on rocks, and sometimes climbing among corals and other invertebrates (Star). They are constantly foraging for micro-organisms and detritus to eat (Star). The African Red Knob Sea Star has a thick, gray body with multiple bright red tubercles that extend upward along each of its five arms, and is found in the Indian Ocean (Star). The Bahama Sea Star has a thick red and orange body, and is found in the Caribbean (Star). It eats soft corals, sponges, tubeworms, clams, starfish, and other invertebrates (Star). The Burgundy Sea Star is burgundy to magenta in color and usually has six arms instead of five (Star). Bat Stars come in a variety of colors, including red, and have webbing between their short, triangular arms, that gives them a bat-like appearance (Bat). Bat Stars usually have five arms, but can have as many as nine arms (Bat).
