This sperm whale died from ingesting a plastic bag, as Marion Vokey correctly answered. The skeleton is at Powerful Beach on Warderick Wells, the Island Headquarters for the Exuma Land and Sea Park. The park is a no catch zone and the snorkeling is particularly good as a result. Many of the reefs are in less than fifteen feet of water and have abundant and varied fish species.

Thanks to those intrepid treasure hunters who participated in our Exuma exploration!
