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.

- old crab pot / habitat 1

Two dead and dried individuals were found on an old, recently dredged, crab pot at Newlyn Marina, Newlyn, Cornwall, 02.06.17 and 04.06.17. The dry specimens were rehydrated and softened for 24 hours in 50/50 seawater and ethanol before they were examined under a microscope and photographed.

The main body of the specimen in the images above is approx. 1.3mm in length. The measurement taken is from the tip of the proboscis to the tip of the tail.

The crab pot on which the species was found was mainly covered in various bryozoans inc. Cellaria, hydroids (Sertularella and Nemertesia antennina), tunicates and sponges. Probably more than 30 species were present in the netting samples that were taken to look at under a microscope. Achelia echinata was the most common Sea spider present and was quite abundant with over a dozen being found.

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.
