4. Oct: Some owners of pet birds...
Some owners of pet birds are surprised to find oval white chalk plates washed ashore as they know them from pet shops where they are sold as supplementary bird food. The plates are backbones of cuttlefish. Cuttlefishbones stay adrift for months and reach the Waddensea originating from France or England. Seabirds like pecking the cuttlefishbones and leave their bill marks on them. Usually the bones stem from the Common cuttlefish which may reach 40 cms in size. Smaller backbones may be from rarer southern cuttlefish species. Living cuttlefish are hardly ever found in the Waddensea, the reason is unclear.
