- old crab pot / habitat 1
Two dead and dried individuals were found on an old, recently dredged, crab pot at Newlyn Marina, Newlyn, Cornwall, 02.06.17 and 04.06.17. The dry specimens were rehydrated and softened for 24 hours in 50/50 seawater and ethanol before they were examined under a microscope and photographed.
The main body of the specimen in the images above is approx. 1.3mm in length. The measurement taken is from the tip of the proboscis to the tip of the tail.
The crab pot on which the species was found was mainly covered in various bryozoans inc. Cellaria, hydroids (Sertularella and Nemertesia antennina), tunicates and sponges. Probably more than 30 species were present in the netting samples that were taken to look at under a microscope. Achelia echinata was the most common Sea spider present and was quite abundant with over a dozen being found.
