Here you'll find some of the smallest creatures living underwater! Many of these animals are almost impossible to notice without special equipment, unless you're looking for them on purpose.

Spanish Dancer is probably one of the most beautiful and well-known nudibranches in the world. As it's name implies, when swimming it looks just like moving red skirts of flamenco dancers.

At Lunch

At the Edge

Some animals underwater are so small we can hardly see them, like this Costasiella sp. nudibranch, which is just about 5 mm.

Pink Lantern

The most beautiful nudibranch I've ever seen - Doto sp., Bali.

Mouthful of babies

This photo was taken in Secret Bay – shallow sandy dive site at the northwestern part of Bali, well famous with its weird and rare creatures. And although Banggai cardinalfish cannot be considered a rare or unusual species in Asia, it attracted my attention. I was well aware that this species is a mouth-breeder, which means the eggs remain in the mouth of the fish until juveniles leave the eggs. But as I was watching this school Banngai cardinals hiding in the group of sea urchins, I've realized that something is going in the one's mouth, but I couldn't figure out, what exactly that was. So, I've decided to take a few photos 'just in case'. To do that all I needed is a sharp eye to catch focus and patience to wait till the fish turns to me with it's mouth full open, while all other fishes are out of the way. When I checked the photo later at the full-screen, I was really surprised to see the juveniles hiding in the mouth of the fish.


Sea cucumbers sometimes look just like nudibranches, and are of the same size.
