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.

A single 7mm long valve was found in a piece of an old American fishing buoy that had washed-up on the shore at Sennen Cove, Cornwall, 15.01.16. The piece of fishing buoy was holed by two 15mm+ diameter holes, one running straight through, and four Isognomon bicolor were found in one of the holes.

Marine Biological Association MBA

The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.

CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders

The CISFBR or Cornwall and Isles of Scilly Federation of Biological Recorders is an independent umbrella organisation supporting independent recorders and recording groups in the county of Cornwall.

Cornish Biodiversity Network

The Cornish Biodiversity Network
or CBN is the largest open source wildlife database in Cornwall that sends open source data to the NBN (National Biodiversity Network). It is a new recording system based on the ERICA database, the largest recording resource in Cornwall. The CBN best supports the activities and needs of the independent recording community and recording groups in Cornwall.

NBN National Biodiversity Network

The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.

The main objective of this website is in furthering environmental awareness and education through the medium of photography. To increase awareness and access to the wildlife of the region and help
people find and identify it. Sometimes the difference between species is obvious but many species can only be determined by observing microscopic characteristics that are specific to any one species.
