Numerous specimens were found under rocks, sometimes with the Australian barnacle, Austrominius modestus, in shallow water at the southern edge of Millbrook Lake, Millbrook, Cornwall, 03.02.18.
The non-native invasive Trumpet tube worm, Ficopomatus enigmaticus, and Conopeum seurati were also present.
The species here was kindly verified by Dr. John Bishop of the Marine Biological Association.
