Abstract

Natural history, aspects of aquarium behavior, and the first dietary data of three widely distributed, but relatively uncommon, Northeastern Pacific sea stars, Poraniopsis inflata (Fisher, 1906), Lophaster furcilliger (Fisher, 1905), and Cera-master patagonicus (Sladen, 1889) are presented. Our observations and analysis indicated P. inflata individuals ate sponges, while L. furcilliger ate sponges and chopped fish, and C. patagonicus appears to be a substrate surface deposit feeder. © 1993 Wiley-Liss, Inc.
