A cormorant dives down on an unsuspecting shoal of fish below.
The mass of sardines off the coast of Moalboal operate a ‘safety in numbers’ strategy whereby the school makes it much harder for predators to isolate a single target.
Using inward lighting, I was able to isolate this perfectly formed Brain Coral. There is great beauty to be found even in common underwater subjects and I am mesmerised by the textures and grooves of this hard coral.
Two beautiful, slender, and curious Blue Sharks off the coast of Cornwall during the British summer.
This Peacock Mantis Shrimp is draped in pink dress of her own eggs. With a punch that has the same power as bullet, she is more than capable of defending her offspring!
Elegant and yet awkward, Seahorses are extremely slow moving fish that blend in surprisingly well with their surroundings.
My dive buddy salutes at the bow of Grand Cayman's most famous wreck: the ex-USS Kittiwake. Decomissioned, auctioned and scuttled off the coast, this famous former submarine rescue vessel was once upon a time responsible for rescuing the black box from the tragic Challenger space ship explosion.

Possessing both brains and looks, the cuttlefish is one of the superstars of the underwater scene and uses colour changes as part of its communication.
The Grey Reef Shark is the big daddy of the reef. The biggest of the reef sharks, they are at the apex of the food chain and, appropriately, they swim around like a boss.

Look closely and you can see the eggs in this jawfish's mouth have developed eyes and are almost ready to be released.

A teeny tiny Golden Roughead Blenny is framed against the blue water of the Cayman Islands.
Framed against a colourful 'disco' background, this minute nudibranch is commonly know as the Shaun the Sheep nudi and is about the size of a grain of rice!
One of the scariest looking fish in the sea. This lie-in-wait predator hides the bulk of his body in the sand and has a specially evolved, upward facing mouth.
With a brutish forehead designed to break coral, Bumphead Parrotfish are not usually associated with good looks. However, shot for below and with a coquettish pectoral fin held out, this one has managed to strike an unusually elegant pose!
An imposing Green Turtle crosses the Red Sea with a pair of Remora stuck to its belly. Their relationship is mutually beneficial: the remoras remove parasites from the turtle and in return get to feed on the host's faeces!
A serene early morning scene as a Southern Stingray swoops over the sand at Stingray City.
Juvenile and small fish often take shelter in and around jellyfish as the jelly's stinging tentacles provide a form of shelter from predators. However, the small fish you see in this image isn't immune to the stings either, and so whilst using the jelly for protection must be constantly alert and make sure it swims in just the right position!
As is often the case in the marine world, it is the male goby who takes on the responsibility of looking after the fertilised eggs. Carefully laid on this delicate tunicate, papa goby will not leave their side until hatching.
This Yellow Pygmy Goby couple live full time on this shell. Endlessly swimming in synchronisation around their tiny home, they never seem to get bored.
Up close and personal with a Dusky Jawfish mouth brooding some rather mature looking eggs - check out the eyes on each one!
One of the most spectacular underwater sights, a male Dusky Jawfish shuffles his eggs in a process that takes a split second.
This Golden Rough Head Blenny may look rather fierce, but in reality he's harmless and smaller than the nail on your little finger!

Jade explores Tubbataha's magnificently healthy reefs along with her underwater camera.
Call me weird if you like but it's a very tight call as to whether I'd rather see a characterful blenny or a shark on a dive. This here is the Spinyhead Blenny, found in abundance in Saint Lucia and always willing to pose.
Nemo (aka False Clownfish) never seem to stay still, a slow shutter speed captures the movement of both the fish and swaying anemone.
Looking down at the stunning shell of a Green Turtle as it swims over the reef.
This devilish-looking Yellowline Arrow Crab looks like he's guarding the gates of hell!
Squid live fast and die young, these two were enjoying their moment under the sun in the shallows at Anse Chastenet.
The curious nature of Blue Sharks combined with their open ocean lifestyle often brings them into trouble when facing the human presence at sea, often with deadly consequences (for the shark). This individual is still swimming but heavily scarred.
Many marine animals will undergo a gender transformation during their lifetime, unusually however, the Ribbon Eel will start its life as a male (with distinctive blue and yellow colouring) and then transition into a lady if it survives long enough (all yellow colouring).
Backlighting translucent fish gives them a personality and style makeover, for instance, this Thorny Seahorse is suddenly looking a little bit evil!

A simple subject, Brain Coral, highlighted using inward lighting and camera rotation - pretty cool!

Everything came together nicely for this shoot: dream model, schooling Boga and Brown Chromis, and a good-looking wreck bum.
The Leaf Scorpionfish is a lie-in wait predator with a slim body and upturned mouth. Part of its camouflage is its ability to gently sway to and fro, with the movement of the water, like a leaf!
Two feather duster worms side-by-side create this interesting, clasped, venus fly trap style shape.
The resident school of jacks is a testament to the wrong conservation measures put in place at the Shangri La marine sanctuary in Mactan.

The eye of this Reef Squid is isolated using super shallow depth of field.
