Greenleaf worms
Eulalia viridis
These beautiful bright green worms can be found on mussel beds and seen crawling across rock-covered barnacles when the tide is out.
They are pretty common but their bright colour makes them a joy to see.

This is an interesting sight as it is thought that the worm's diet is primarly moribund or dead animal tissue.
Below is a video of the same.
