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.

Tetraselmis marina syn. Prasinocladus marinus.

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.
