Recording Marine Life

Record your sightings

Warming seas, non-native invaders and human activities are all affecting our marine environment. Records of marine life are needed to inform decision-makers, to track changes, to find out why things are changing and, let's not forget, because recording is fun!

How to record marine life

New to recording? Read our recording marine life guide.

MarLIN holds and makes available records of marine life from professional surveys and volunteer recorders. All records are passed to the National Biodiversity Network for display on the NBN Gateway. MarLIN provides marine life information and facilities for volunteer recorders including online recording. The Sealife Signpost and identification guides support these online resources.

Other schemes

MarLIN collaborates with other recording schemes especially Seasearch and the Rare Fish recording scheme. The Sealife Signpost directs users to other marine life recording schemes.
