Sea world

Look at these cool creatures!

We have tied alongside in a Marina and I was walking out along the pontoon when I noticed these fab little organisms. The 'mouths' at the entrance of the tubes open and close.

I have no idea what they are, but I thought this was so great I had to blip them!

Update- apparently these are young sea squirts, Ciona intestinalis!! I've learned something new today :)
