A coconut was found washed-up on the beach at Newquay, Cornwall, by Tracey Williams in March 2014.

Here's the important bit and the correct information -

Tracey Williams took the coconut to Dr. Paul Gainey who found it contained boring molluscs and these were thought to be Martesia striata, as only this species had been reported before. On closer examination and using literature produced by Ruth Dixon Turner the species ws identified as Martesia fragilis by David Fenwick, which was later confirmed.
