Nemo, or the False Clown Anemone Fish, is a relentless mover in his host anemone and this was a tricky moment to freeze.
Backlighting of this Thorny Seahorse gives it an entirely different, more malevolent, character.
With an ornate carapace design, Harlequin Crabs are beautiful and hard to miss. They rely on living in symbiosis with a stinging anemone for protection.
Although intricately patterned, Dragonets are almost imperceptible to the naked eye as they shuffle across the seabed.
The movement of the anemone and False Clown Fish are captured using a slow shutter speed.
This bristly fellow is the Hairy Squat Lobster and it weighs in at under 1.5 cm long. All that hair actually serves a purpose, trapping potential food which the squat lobster can then harvest. Imagine if you had to catch your food in your hair before eating it!
This White Mantis Shrimp is so rare scientists haven't even given it a name yet.
Pipefish are slow swimmers and move in a vertical, head down position in a bid to fool potential predators.
A fantastically pink Frogfish with an even pinker lure on its forehead.
Porcelain Crabs, as the name suggests, are pretty brittle things and prone to losing limbs in battle. They do however have (relatively) massive claws for fending off adversaries.
One of the most sought after and weird looking fish out there. The Hairy Frogfish is a superstar of the underwater macro scene.
Cardinal Fish are one of many fish that mouth brood their eggs. This task usually falls to the male.
Closely related to Scorpionfish, the Waspfish is a lie-in-wait predator who's slender body works well with backlighting.
A slow shutter speed gives this shot of Nemo a surreal effect. Oh and the Damselfish in the back wouldn't stop photo bombing.
Moray Eel faces always seem to hover somewhere between surprised and grumpy.
Cuttlefish are highly intelligent and communicate using colour changes and their tentacles. I think this one is saying hello.
Fish portraits are notoriously tricky - I like the eye contact achieved with the wrasse in this image.
I captured this Damselfish just as it charged me in a territorial dispute. Needless to say, the Damselfish won.
Elegant and yet awkward, Seahorses are extremely slow moving fish that blend in surprisingly well with their surroundings.
