An 8mm long juvenile specimen of Anadara transversa was found with seven specimens of Argopecten gibbus, the Atlantic calico scallop, inside a small, plastic, toy speedboat that had washed ashore in Ireland. Specimens were found by Liam Mac Namara at Fanore Beach, Co Clare, Ireland, 18.07.16. It is likely the toy boat was lost or lauched in Florida, USA.

Specimen above was purchased as a reference specimen as the species is potentially a rafting species and may arrive in the UK on flotsam from the Gulf of Mexico and the SE coast of the United States of America. The specimen is in a private collection in Cornwall and was purchased for displaying this non-native species here. Images taken 15.01.16.

The specimen above was found after a storm by Steve Rosenthal, on Turner Beach, Captiva, Florida, USA. 04.12.2009. The shell typically has one valve larger than the other.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project recommends the following websites and works with the following bodies and organisations.

Conchological Society of Great Britain and Ireland

The Conchological Society of Great Britain and Ireland
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.
