Stramonita floridana, the Florida rock snail, has washed-up four times on American fishing floats around the UK cost in Dec./Jan. 2015/16. One juvenile specimen was found in Kent, four specimens were then found on a float in Dorset, then one in Cornwall, and then two on a single float in Dorset. What specialist beachcombers are finding is the tip of the iceberg. It is not known if the species can survive in the UK, but the have colonized areas of Spain already.

Helping to understand, identify, record, and conserve molluscs.

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.

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 taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.

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.
