Janolus species

Barely 1cm in length, and in an area of basically nothing I was amazed that my guide managed to spot this tiny nudibranch at all, there appeared to be nothing around but muck!

Another example of something I would have preferred to shoot with the 105mm lens + a wet diopter, but had to make do with my 60mm lens.

Lembeh Straits, Sulawesi, Indonesia, July 2013

A lot of floating debris from other divers fin kicks make photography rather challenging at times
