Scrobicularia plana
The shell has numerous fine, concentric rings and grooves. It is dirty white, yellowish or greyish in colour, and is flat, thin and delicate in form. Length 6.5cm.
It is found in sheltered, brackish habitats, like estuaries and muddy shores where it burrows up to 20cm, leaving behind a star-shaped tell-tale impression on the surface. It is a deposit-feeder, and when the inhalant siphon is extended it is often eaten by crabs, fish and wading birds, but it is regrown fairly quickly. Common and widespread all around the UK.

I’ve been enjoying your shells. The names are delightful, and creative. “Peppery furrow” seems a very fancy name for such a plain shell, but the name certainly got me to give the shell a second look.

This may sound a bit odd, but the grooves in the shells and the colors remind me of how the exterior of many of the clay pots my brother threw on the wheel. Nice texture and color.

Thank you, Sandy 🙂 Now you mention it, the texture does look like clay pottery.
