Did you know that Brydeswhales are 12-14 m long and that they are a lot smaller than the Blue whale? Although very big, they are extremely nimble and fast. Picture taken under license of the Sri Lankan Government.
Did you know that clownfish (Nemo) have many relatives in different parts of the world?
Being in the water with Orcas / killer whales is nothing short of amazing! It is a very special feeling to be in the water with these highly intelligent blackfish!

It is found on reefs in the Indian and Pacific Oceans, from the Red Sea in the west to Samoa in the east?
I really love clownfish, especcially when they are in a nice-coloured anemone. Did you know that clownfish co-exist with the anomone? Other predators get stung by the anemone, except for the clownfish, they in turn, keep the anemone clean!

An incredible site to behold, let alone be part of... Being immersed in such a big school of jacks in truly breathtaking! Taken in Bali, Indonesia.
The nudibranch, which is kind of an underwater snail, cannot be compared to their land-based counterparts in any way, due to colours and the way they look, from very very small, to pretty big. So far, about 3000 species of nudibranch are known.
This honeycomb moray eel (Muraena melanotis) was being cleaned at a cleaning station in Bali. I used a snoot to light the right side of the face, giving depth to the image, while my left strobe was on min power to get just the littlest of fill light.
Small, colourful fish swimming over the hard corals in Marsa Alam. It is incredible how many colours there exist underwater, and how well these colours correspond to the corals beneath!

Did you know that Scleractinia (also stony corals or hard corals), are marine animals that build their own skeleton and that corals, like the dome and plate species, are more bulky and may only grow 0.3 to 2 cm (0.1 to 0.8 in) per year?
Did you know that Mandarin fish mate just after sunset and that they live in small populations and are very skiddish? You can only find them using red lights, which they can't see.. The mating only lasts for a few seconds.
The Red Sea in Egypt holds a lot of nice views, above and below! In this over/under shot, I love that you can see how the water gives a different view. Check out the pink coral on the left, above and below water.
