Specimen found in scrape sample of marine fouling taken from pontoons at Newlyn Marina, Newlyn, Cornwall. 28.04.18.

The species here was found in a scrape sample taken from pontoons at the marina. What tends to happen with scrape sampling is that in removing some of the sea squirts they are damaged and as a result copepod parasites can be released into specimen containers, parasites such as Haplostoma eruca and Pachypygus gibber. Haplostoma eruca is not a commonly reported species and is found in the intestines of Ciona intestinalis, the Yellow vase sea squirt.

Thanks go to Myles O'Reilly for his help in confirming this species.

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.
