An educational resource dedicated mainly to the photography
and diversity of marine life that can be found in coastal waters
and intertidal areas of Great Britain and Ireland by David Fenwick.

Chama macerophylla Gmelin, 1791 - Leafy jewel box clam (Marine bivalve images)
A verified specimen of this species was found washed-up in Ireland, March 2017, cemented to an item of plastic that has probably drifted from the southern states of the USA.

The Chama macerophylla here was found by a diver in 80-90 feet of water, it was on a rock pile just off the Blackthorn Wreck, Pinellas County Artificial Reef #2, West of the mouth of Tampa Bay, Florida, USA, in 1988.

The small boring bivalve mollusc in the center of the shell is Choristodon robustus.

Chama macerophylla is included here as a number of Chama are rafting species and therefore have the potential to arrive in the UK on items of flotsam via the Gulf Stream.

Shell bases up to 60mm in length were found on a Stone crab trap that had drifted from Florida, USA to the Lesceave end of Praa Sands, near Helston, Cornwall. SW 58522 27590. 10.11.15.

The images here are of a left basal valve that is 60mm in length. No right valves of Chama macerophylla were found on the trap, and Chama macerophylla cannot be determined on size of the valve alone. However, C. macerophylla does occur with C. congregata, so is likely.

The bivalves Chama congregata, Chama florida and Isognomon bicolor, the Bicolor Purse-oyster were also found on the same stone crab trap. The bryozoan Akatopora tincta was also found in a crevice on the trap.

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.
