Laura Verhegge in October 2005, collected two of these specimens while taking samples of invertebrates in the area where the tidal current turbine generator is to be installed. The diameter including legs is about 1cm. Note the short stubb as it should have 8 legs.  This video was taken with a microphotography apparatus. They were both found at 20 metres depth in association with the hydroids and the club tunicates.
