Species found on Lithothamnion in an uppershore pool at Skilly, Newlyn, Cornwall. 17.03.17.

A small scrape sample was taken and placed in a tube for examination under a microscope. The species was found not to be encrusting the Lithothamnion as it appeared to do but was made up of clear filaments with green cells at their tips. Under a stereozoom microscope the alga looked like it was made up of very fine bundles of cotton wool. The images above were taken of one of these bundles. The green cell tips are approx. 20um in length.

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.
