Swanny Armina, found on the underside of a Sea Pen. Photo taken by my dive buddy Dennis Hutson (I didn't have my camera to take a shot, however I did observe this sea slug, as I was helping with photography- I hovered next to Dennis holding my torch light on subject). Photo was taken at 15m, about 10m away from a main structure; over sandy patch, with a small weedy/rocky patch. The sea slug was originally on the underside of the sea pen, it inadvertently dislodged, we waited a minute as it moved across some structure, which is where the photos were taken (right next to the sea pen). Size was approx; length 40mm, very wide, maybe 30mm (before it stretched out and started moving). Dennis noted he has NEVER seen one before in >25 years diving. my first obs as well. :)
