Specimen above found whilst dissecting an odd looking Ciona intestinalis, Yellow vase sea squirt, which was whitish and distorted. The Ciona was collected from a pontoon at Newlyn Marina, Newlyn, Cornwall. 29.06.16.

At Mylor Marina the species was likely from Ciona intestinalis, the Yellow vase sea squirt; but Ciona intestinalis and Ascidella aspersa were collected together. Specimens were found in the sediment in the bottom of the collection container after straining through a 1mm square hole plastic sieve (a 99p one from a supermarket). The strained material was washed and placed in fresh seawater and looked at under a stereomicroscope. It is likely the seawater in the collection containers had become anoxic and the copepods had come out or fallen out of the tunicates. Specimens were live when photographed.

APHOTOMARINE supports open source data recording and sharing for the benefit of wildlife, recorders, research, science and education. The project recommends the following websites and works with the following bodies and organisations.

The Marine Biological Association or MBA, based in Plymouth, is one of the world’s longest-running societies dedicated to promoting research into our oceans and the life they support. Since 1884 the MBA has been providing a unified, clear, independent voice on behalf of the marine biological community.It has a growing membership in over 40 countries.

The National Biodiversity Network or NBN is a charity that supports open source data sharing and recording supporting conservation, science and education. "Why do recorders need open source?". Simply because it supports the core values of wildlife recording and the free use of records and data over a very wide network that includes partners like the Natural History Museum.

The taxonomy used here is based on that of the following database, which is also used by the MBA, NHM and the NBN.

The World Register of Marine Species or WoRMS.
