This 17 March 2018 video says about itself:
Queen Scallop, Aequipecten opercularis, in natural sandy seabed, Bovisand, Plymouth, England. Filmed in time-lapse they have been placed in front of the camera but soon decide to leave – pumping themselves up as if ready to suddenly jet off. Various periwinkle snails can be seen burying themselves in the sand. Queen scallops are edible and part of a big fishery off the Isle of Man.
On 15 December 2020, warden Joeri Lamers reported that many queen scallops had beached on Terschelling island. So many that he suspects they now live not far from Terschelling, where they were unknown as a resident species before.
