I love the colours, patterns and sculpted look of Turban Top Shells – Gibbula magus (Linnaeus). I found loads of them on Weymouth Beach recently. I was surprised to find them there because usually I find only Slipper Limpets. The Turban Tops were all sorts of sizes and conditions. Some were intact with beautiful red zig zag stripey patterns. Others were worn, broken and faded. Many were covered in a strange organic-looking textured reddish-brown coating.
At the top of the sandy shore there were low-lying mounds concealing an old strandline of accumulated detritus that included large quantities of well-rotted seaweed. Winter waves had been eroding these deposits away and releasing the buried Turban Tops. The whole process was being speeded up by numerous pairs of large black crows that were systematically searching the beach for food. The bird pairs had divided up the territory and were leaving no piece of debris unturned in their patch.
There are earlier posts about these shells and the animals that occupy them. Click here for more information about Turban Top Shells in Jessica’s Nature Blog.
