Report a jellyfish sighting

Your sightings contribute to marine research and are essential to monitor jellyfish populations around the UK. Jellyfish are important indicators of change in our seas and we use this data to monitor the health of the ocean.


Report a marine turtle sighting

We are interested in hearing about the marine turtles you spot around the UK. Your turtle sightings are used to gain valuable insights into the health of our ocean. If you do find a hard-shelled turtle, DO NOT return it to the water, it is likely they are in cold water shock. Once you report it, we will contact you and try to recover it to give it the best chance of survival.
