Tuesday Not Nudi

Running slightly low on slugs til I get access to my archive again so here's something a lot of people mistake for a nudi. This is a flat worm - bedford's flatworm to be precise. In addition to the spectacular green and pinky red striping these have a trick most nudis don't.

If they choose to, they can swim through the water by undulating their bodies. Happily they don't do this often which means when I find one I can relax and take my time setting up the photo. This chap was hidden away on a night dive and remained chilled out as I photographed him by torchlight.
