Abstract

We report new geographical and bathymetric occurrence information for several species of brisingidan asteroids (Asteroidea: Brisingida) in eastern Canada. We recorded Brisinga costata, Freyella microspina and Novodinia americana in Newfoundland and Labrador (NL), extending the geographical ranges of these species northward. Brisinga costata and F. microspina occur up to 350 m shallower in NL than elsewhere in their published ranges, while N. americana occurs 567 m deeper. We also confirm the presence of Freyella elegans, a possibly cosmopolitan species found throughout the North Atlantic but not previously reported in Canadian waters.
