Snails of the sea

Last week we spent some time on the shore in Whitehaven and came across some empty Flat Periwinkle shells (or littorina obtusata to give them their full Latin name).  These small marine molluscs are widespread and common along the UK coast and can usually found on rocky shores amongst the brown seaweeds.  They grow to about 1.5 centimetres and can occur with orange, yellow, brown, grey or even chequered shells.

A little way further along the shore we found an occupied shell with a periwinkle exploring its surroundings.  Check out the video on our instagram page.

When you’re next on the shore why not stop your stroll and take a while to look closer at the amazing creatures you can see?
