Chalk reefs extend up to 6km offshore and support some of the best and most diverse reef habitats in the UK, including rocky shores, kelp forest and offshore chalk reefs.
Rocky shores are covered with seaweeds which are grazed upon by limpets and winkles. They form an important link in the food chain between the marine and land environments. The shores of Flamborough Head are home to 112 species of seaweed and over 270 marine animals, including the piddock which is a specialised mollusc which bores into the chalk shore.
