Family: Oreasteridae
Size: Up to 30 cm (12 in) in diameter
Depth: 0 – 183m (0 – 600ft)

Distribution: Eastern Pacific (Gulf of California to Peru, including the Galapagos).

Identification: A massive, heavy-bodied sea star that looks like a studded cushion.

• Shape: They have a very thick, inflated central disc with five relatively short, triangular arms (pentameric symmetry).
• Color & Pattern: The coloration is highly variable, but often features a deep red/burgundy base covered in an intricate, reticulated (web-like) pattern of grey or white.
• The Spines: The upper surface (aboral side) is studded with large, rigid, immobile spines or "knobs" (tubercles) that are usually bright red or orange.

Behavior: A slow but ecologically important bottom-feeder.

• Diet: They are opportunistic omnivores and scavengers. They feed on benthic algae, microorganisms, and even small invertebrates like pencil urchins.
• Habitat: Commonly found resting in the open on rocky reefs, rubble, and adjacent sandy plains.
