The parasite Sphaeronella danica? was found in the marsupium (egg pouch) of female specimens of the corophiid amphipod Monocorophium acherusicum. collected from the pontoon at Saltash Green, Saltash, Cornwall, 14.10.22.
The sample containing the amphipods consisted of scrapings from the submerged outer section of a car tyre being used as a fender on the pontoon mentioned above. The hydroid Ectopleura larynx formed the largest part of the sample, along with other smaller hydroids and a few non-native and native tunicates / sea squirts.

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.
