Images of species taken at various locations across the south coast of Cornwall; the best place to find this species is at Par, near St. Austell, Cornwall, where tests can be found in large numbers on the strandline after storms, and where live animals can similarly be found washed up on the lowershore. Species can also be found in Mounts Bay from Newlyn to Marazion.

Species also found in soft sediment on the lowershore at Batten Beach, Mount Batten, Plymouth, Devon; by Dr. Keith Hiscock of the Marine Biological Association, and at the MBA Batten Bay Bioblitz 2014. 12.09.14. Species lives under sand, species can be found by looking for two small holes on the surface of sand, a few inches apart. The species also has a commensal bivalve, Tellimya ferruginosa, Rusty montagu shell, that can be found close to the anus of the species, as seen in the images above.

Scientific and European Names:
Echinocardium cordatum, Sea potato, Seeigel herzigel, Zeeklit, Oursin coeur, Erizo corazon, Spatango a forma di cuore.

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.

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.
