We want to hear about the wildlife you spot at the coast and at sea, especially basking sharks, marine turtles and jellyfish in UK and Irish waters.

Please click on the options below to report your sightings. Your sightings provide vital information for our scientists and help us come up with solutions to protect our precious sealife.

(To report a sighting you will need to log in to the website, this helps us ensure the validity of the data. If you do not have an account it’s easy to create one from the ‘register’ link on the login screen)
