    Turtle insights

    In 2025, twelve turtle sightings were reported to us: nine leatherbacks, one loggerhead, and two unidentified. All but one of these was seen in the sea, with only one stranded turtle reported.

    These sightings fed into the UK Turtle Implementation Group's annual report, of which we are a leading partner.

    This report was updated in spring 2026, with the latest turtle sightings data from 2025.
