A walk along the seashore below the cliffs between Cliff End and Fairlight at low tides often reveals glimpses of the hidden life of the sea. This morning I came across something I’ve never seen before, a Sea Mouse [Aprodite aculeata]. This was quite a big creature, about 4 inches long, the pictures show the segmented under surface and the bristly upper side. Sea Mice are brisle worms which are normally buried in the sand , they live on other worms such as ragworms. They are evidently quite common.
