So here’s pic 2 from my trip to Sipadan/Mabul/Lankayan.
From memory I think this guy was on Seaventures oil rig dive site just off Mabul.
I used the same kit as before, Canon 7D in a Nauticam housing and 2 Inon S2000 strobes
For those that care, the frilly bits on the back are the nudibranchss gills and the
2 pointy bits on the front are called rhinophores, basically the slugs eyes.
