Description
This dataset details approved records from the Shark Trust's Great Eggcase Hunt, active since 2003.

Data comes from ad-hoc records, regular surveys and data uploads from partner organisations. Please note that not all records are verified, but this has been indicated in the extended Measurements or Facts.
