Common name: Starfish
Forcipulatida is an order of starfish that includes some of the most well-known sea stars, such as the iconic Asterias rubens. Members of this order are characterized by their robust and often spiny appearance, with a distinct central disc and usually five arms, although some species can have more. They are found in a variety of marine environments from tidal pools to deep-sea habitats. Forcipulatida species are important predators in their ecosystems, feeding on bivalves, snails, and other invertebrates. In the aquarium, they can be fascinating additions but require a well-established tank with plenty of live rock and a stable environment. It's crucial to ensure that any species introduced is compatible with the existing tank inhabitants and that they are not prone to preying on coral or other ornamental invertebrates.
