The endoparassitic copepod above was found on the nudibranch Acanthodoris pilosa. The sea slug was found under a rock in a large shallow pool on the middleshore in front of Newlyn Green, Newlyn, Cornwall, 30.10.18.

What is seen on the sea slug is the egg masses of the female copepod. The female and male/s are inside the animal. The images of the female are not entirely representative for Acanthodoris pilosa is quite a tough animal which made the dissection to confirm the species of copepod very tricky indeed.

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.
