Brittle star, also called serpent star, any of the 2,100 living species of marine invertebrates constituting the subclass Ophiuroidea (phylum Echinodermata). While most common starfish have tubes under their limbs that move the entire body, Brittle sea stars use their slender and mobile arms to drag their body across the ocean floor.
