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.

Specimens were found growing with the marine lichen Lichina pygmaea, at Battery Rocks, Penzance, Cornwall. 26.04.16.

Identification made using a microscope and Seaweeds of the British Isles Volume 2 by Elsie M. Burrows.

On looking at ERICA, the Cornish records database I found three very old records for this species, two were from Penzance, and one, a 1880 record was also from Battery Rocks, Penzance. An earlier record, November 1839, was by J. Ralfs, at Penzance.

This is certainly an under-recorded species because of the need for microscopic identification. Fine green algal species can also grow together as a colony so more than one species could be involved, here the specimen taken was growing with Blidingia minima.

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.

World Register of Marine Species or WoRMS

The World Register of Marine Species or WoRMS.

AlgaeBase

AlgaeBase is a database of information on algae that includes terrestrial, marine and freshwater organisms.

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.
