Colour in alcohol nearly the same but somewhat faded. Tube feet densely crowded ventrally, present in ambulacral and interambulacral areas. They are wide, short with a terminal disc 0.8–1.2 mm across. Dorsally the tube feet are small, much less numerous than ventrally, without terminal disc and scattered without alignment. Mouth surrounded by 20 very large, bushy tentacles; anus surrounded by five groups of three to four papillae. Calcareous ring with radial plates at least twice as long as the interradial ones; interradial plates with a sharp central tooth, radial plates quadrangular with a central notch on the anterior margin (figure 9A). One very long Polian vesicle (one-quarter of body length) and very long tentacle ampullae (one-fifth to one-sixth of body length). One very short stone canal ending in an ovoid madreporic plate.

The species lives in the intertidal zone (Codoceo, 1976; Ramirez and Osorio, 2000). It is attached to rocks in the surf zone or concealed under large stones. When it lives in coarse sand bottoms it is covered with various debris (pebbles, pieces of algae, calcareous tube worms, etc.). The bushy tentacles are extended in the water column. However, intestinal content reveals mainly coarse detrital material (Codoceo, 1976). The species reaches high population densities: 20–
