Rays were swimming in our seas when dinosaurs walked along British shores.

The undulate ray can still be found along the Jurassic Coast, but little is known about their habits and movements in the wild.  This project is exploring the lifestyle of the undulate ray, using computer recognition as part of a long-term monitoring of an undulate ray population on the south coast.

Most subsequent re-sightings of undulate rays are within a few metres of where the ray was previously seen.  We are now concentrating the study on rays seen between Portland and St. Albans Head.  We hope to find out more about how large their home territory is, where they lay their eggs and where the young develop before people see them as relatively large juveniles.
