Some rocky shore web sites!

This UK site has just about all the information you could need.

There is also a Swedish site with lots of information on many of the organisms you are likely to meet on the rocky shore in the UK.

Finally, here is a site that describes a rocky shore in Dorset. It has good habitat information and places the organisms where you might expect to find them on the shore.

If you want some detailed information about many rocky shore organisms try the British Marine Life Study Society and the Marine Life Information Network.
