More on sea squirts

Many of you know Lorna and I are particularly keen on rockpool creatures. On our last expedition at Bruichladdich we found many sea squirts which seemed to defy identification so I contacted the Marine Biological Association in Plymouth and spoke to the very helpful project officer who has provided some interesting information. I'll repost the photos here with the additional information.

The non-native species Corella eumyota. Distinguishing features are the smooth curve to the gut which you can see through the body, orange tips to the siphons and the second lower siphon is on the right of the body. 

Bortylloides schlosseri  with the large openings of a boring mollusc growing beneath the squirt. You can actually see the eggs. This photo had the experts puzzled for a while!
