and diversity of marine life that can be found in coastal waters
and intertidal areas of Great Britain and Ireland by David Fenwick.

Inodosporus octosporus is commonly known as Cotton or Milk disease of Palaemon serratus, it is very likely the species present here, although there are a number of other fungi that also affect prawns and can turn the muscles white.

This species has sporophorous vacuoles with eight spores and these can be seen using a light microscope on smearing a slide with mashed muscle material then staining with Methyl Blue stain. High magnification over x400 is needed and ideally oil immersion and phase contrast techniques are used to look at the spore containing vacuoles.

The specimen was found on Cellars Beach, Noss Mayo, Devon, 13.07.18 during the Marine Biological Association bioblitz 2018 at Newton Ferrers and Noss Mayo.

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.
