Survey data

Diver's records are a valuable source of information about the wildlife close to the British coast line. Over the years the Lancashire group has surveyed numerous sites, and collected records of the types of plant and animal they found, and in what physical environment they found them. A small number of these records have been collected below:

Please feel free to compare and contrast the records here with any you have taken. Many species are seasonal, so the date of the survey is as important as the depth and substrate!

Shallow waters (to 10m) tend to be dominated by seaweeds (as long as there is a firm substrate for them to hold onto). Beneath this depth lie a range of filter feeding animals - scallops, bristle worms and sea pens on soft sediments, anemones and dead men's fingers on hard substrates.
