Add a record

If you see a mitten crab, a sighting report requires:
- a clear photograph of the individual
- the number of crabs seen
- the exact location, time and date of the sighting

If you have the iNaturalist app (available on iOS and
Android), a useful tool to record any wildlife sightings both in the UK and overseas, you can submit the record directly on the app or via the iNaturalistUK website.

You can download a Mitten Crab ID guide from NNSS here.

You can also upload records to iRecord, which like iNaturalistUK, shares the data with the NBN Atlas, a national biodiversity database.

Alternatively, you can email the Marine Biological Association through dassh.enquiries@mba.ac.uk with your photograph, location, time and date of the sighting and they can record the sighting for you.
