Pachypygus gibber (Thorell, 1859) - A notodelphyid copepod (Copepod images)

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.
