Species may be found attached to kelp holdfasts and to flotsam that has drifted across the Atlantic. May also occur with Hiatella arctica, Wrinkled rock borer, on flotsam and kelp holdfasts.
Large specimens that appear to be this species, which may or may not be found on plastic flotsam, may be Pododesmus striata.
The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
