Scientific Name: Ophiothrix suensoni

Description: The spiny brittle starfish has a distinct appearance characterized by its slender arms covered in numerous small, pointed spines. It typically has five arms, although some individuals may have more. The coloration of spiny brittle starfish can vary, ranging from shades of brown and red to yellow and even purple. Its central disk, where the arms originate, is relatively small compared to the length of its arms. The spiny brittle star uses its long, flexible arms to move gracefully across the substrate, capturing food particles and sensing its environment using its sensitive tube feet.

Habitat: The spiny brittle starfish is found in various marine environments, including rocky reefs, coral reefs, and sandy seabeds, primarily in tropical and subtropical regions. It inhabits shallow coastal waters, often occurring in intertidal zones and down to depths of around 200 meters (656 feet). Spiny brittle stars are commonly found hiding under rocks, within crevices, or among algae and seagrass beds, where they can seek shelter and avoid predators while scavenging for food.

Behavior: The spiny brittle starfish is a filter feeder, using its tube feet to capture plankton and other small particles suspended in the water column. It extends its arms into the current and moves them rhythmically to create a flow of water that carries food particles towards its mouth located on the underside of its central disk.
