Brittle star, also called serpent star, any of the 2,100 living species of marine invertebrates constituting the subclass Ophiuroidea (phylum Echinodermata). It is often found in empty shells or under stones, from the littoral zone down to 350 metres. Hutchins, D.A., Teyssié, J-L., Boisson, F., Fowler, S.W., & Fisher, N.S., 1996. BioMar biotope viewer: a guide to marine habitats, fauna and flora of Britain and Ireland. Dense brittle star beds form an area of considerable physical complexity with many crevices and places to shelter. The larvae metamorphose into juvenile brittlestars whilst still in the plankton. However, increased desiccation through exposure to air and sunlight may kill part of the intertidal population. Growth rate estimates vary considerably. Suspension feeders are important in coastal ecosystems because they can remove large amounts of suspended particulate matter (Davoult & Gounin, 1995).
