The acrochaetioid algae above which might be Audouinella thuretii, it was found growing as an epiphyte on the red algae Cystoclonium purpureum, which was found as a drift weed at Lariggan Rocks, Penzance, Cornwall. 06.08.16.

Acrochaetioid algae cannot really be identified from images and apparently even with samples some cannot be reliably identified by experts. Images are placed here merely to illustrate examples of acrochaetioid algae.

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.

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.

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 World Register of Marine Species or WoRMS.

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