This is the egg case of the Alder’s Neckless Seashell (Plinices polianus) which is a member of the prosobranchia section of the gastropods.
The Alder’s Neckless Seashell itself resembles the egg case somewhat, but has a shell in the centre of the ring which houses the mouthparts.
It feeds on cockles; it moves over the top of a cockle and then dissolves the meat of the cockle while covering it.
After storms at sea, lots of these egg cases become washed up on beaches and these provide an irresistible food for gull species.
The information for this piece would not be here had it been for the intensive research by Pink Fairy, of whom I am very grateful. Thank you.
