Did you know that hermitcrabs have 'social networks' to find new shells? When a hermitcrab finds a new, bigger shell, different individuals, will gather around and form a waiting line from big to small? They move into a bigger 'home'
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!
Did you know that Mandarin fish only reproduce around sundown? They swim up in a matter of 2 seconds and release their eggs and sperm.
Did you know that The Atlantic goliath grouper or itajara (Epinephelus itajara), also known as "jewfish"? They may reach extremely large sizes, growing to lengths up to 2.5 m (8.2 ft) and can weigh as much as 360 kg (790 lb).
Did you know that the green humphead parrotfish (Bolbometopon muricatum) is the largest species of parrotfish?
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 the yellow boxfish (Ostracion cubicus) can be found in reefs throughout the Pacific Ocean and Indian Ocean as well as the south eastern Atlantic Ocean? And that It reaches a maximum length of 45 centimetres (18 in)?
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.
The Red Sea in Egypt is also called 'The Cradle of Life' by many. I do feel priviledged to be allowed into this magical place!
Did you know that this octopus usually burries themselves in the sand, making it next to impossible to get a good photo of them? Photographed with a +5 Sea and Sea wet diopter and snoot.
Did you know that there are thirty species of clownfish recognized? and that Anemonefish are omnivorous and can feed on undigested food from their host anemones, and the fecal matter from the anemonefish provides nutrients to the sea anemone?
Did you know that the Red Sea is also called "The Cradle of Life"? Photographed in Ras Mohammed, Yolanda/Sharks Reef.

This Hermitcrab was photographed in Sardinia. Did you know that most species have long, spirally curved abdomens, which are soft, unlike the hard, calcified abdomens seen in related crustaceans? There are approx 1112 species of Hermit crabs.
Did you know that, despite the typically small size of its members, the family Gobiidae is the largest family of marine fishes, being the home of over 2,000 species? This lemon drop Goby is typically a very shy critter and is very small (it is sittin
Did you know that these are called boxer crabs, boxing crabs and pom-pom crabs? And did you know that they are notable for their mutualism with sea anemones, which they hold in their claws for defense? In return, the anemones get carried around which
