The Anchistrotos zeugopteri covered Common Topknot, Anchistrotos zeugopteri, above was found under a ledge at Battery Rocks, Penzance, Cornwall, 14.08.18. The parasite was found across the dorsal surface of the host but concentrations were seen around the gill flap, nostrils and fins.

This species was discovered in an image of the host years after the original image was taken. It is thought the species is Anchistrotos zeugopteri, which is usually found on the fins and head area of the Common Topknot. The host was originally found under a rock in a pool on the lowershore at Spit Point, Par, St. Austell, Cornwall. 10.05.09.

This species has also been known as - Bomolochus zeugopteri and Taeniacanthus zeugopteri.

It is hoped that this species will be found again and more detailed images will be taken of the parasite.

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.
