An Australian surfer managed to capture the moment he was circled by a great white shark on camera.
The nerve-wracking video was shot at Manly Beach in Sydney, which lies on the shore of the Tasman Sea between Australia and New Zealand.
It's a popular haunt for the city's surfers, but this one gets more than just big waves when he goes out to sea.
Using a waterproof camera, he takes a look under the surface as he paddles fairly close to the beach.
Clear in view is the grey shadow of a great white shark, its distinctive fin appearing ominously through the murky water.
The surfer's breathing becomes more panicked and his paddling speeds up, as he tries to move into shallower waters to get away from the threat.
Somehow remaining relatively calm, he moves towards the shore slowly. Taking another look for the shark, he finds that it's gone.
Great white sharks have a fearsome reputation, but there's a chance that this particular one was just curious. Then again, like most people, this surfer clearly wasn't willing to take the risk.
Attacks are rare but not unheard of in the area. The last fatal attack in Sydney was in 1963, but earlier this year, further up the coast in Ballina, New South Wales, Japanese surfer Tadashi Nakahara was killed after he was bitten in the legs by a shark, believed to be a great white.
The world’s best shark diving locations
The world’s best shark diving locations
There are many shark species which can be sighted off the coast of Australia, including great white sharks, grey nurse sharks and reef sharks, but Ningaloo Reef on the western side of the country offers the chance for you to get in the water with the world’s biggest fish, the whaleshark (pictured). From April to July, these massive creatures can be reliably found near the surface, gulping down huge mouthfuls of microscopic food, and this is when you can snorkel with the behemoths.
2/10 Great Britain
The good old UK has its own world-class shark encounter, and not just any shark, but the second-largest in the world - and best of all, you don’t even have to be a diver to see them! In the summer months, huge basking sharks (pictured) appear off the coast of Cornwall and around the Isle of Man, feeding on plankton at the surface, offering a close encounter to snorkellers.
Mexico has several shark-diving spots up its sleeve. Guadalupe Island, which sits 150 miles west of the Baja Peninsula in the Pacific Ocean, is considered the ultimate location to cage-dive with great white sharks (pictured), blessed as it is with clear blue waters and plentiful food sources. On the other side of the country, in the waters off Playa del Carmen in Cancun, you can dive with migrating female bull sharks between November and March.
4/10 The Bahamas
The Bahamas is known as the shark-diving capital of the world, mainly due to the fact that Caribbean reef sharks (pictured) can be regularly sighted in the deep waters off the scattered islands, but more recently two specific areas have become a Mecca for shark divers. Tiger Beach, off the west coast of Grand Bahama, is a prime site all year round for - you guessed it - tiger sharks, which cruise in the shallow waters over an immense sandbank and will come extremely close to divers, while off Bimini, a similar sandbank is home to immense great hammerhead sharks in February.
The Egyptian Red Sea is home to several species of shark, including grey reef, scalloped hammerhead, silvertip and even the odd whaleshark or tiger, but one of its most-majestic inhabitants is the oceanic whitetip (pictured). This highly distinctive shark, with its vast, rounded pectoral fins resembling airplane wings, can often be sighted off the offshore marine park islands of The Brothers, Daedalous and Elphinstone in the winter months, though they have been seen all year round.
6/10 South Africa
Mention ‘South Africa’ and ‘sharks’ and people immediately think ‘great white sharks’, but this country offers far more than just the opportunity to cage-dive with the ultimate apex predator off Dyer Island and Geyser Rock near Gansbaai. You can also get in among packs of blacktip sharks (pictured) and ragged tooth sharks off the KwaZulu-Natal coast on the eastern side of the continent, and of course, from May to July, this is a prime location to sample the Sardine Run, when billions of sardines migrate northwards and attract hundreds of sharks, not to mention whales, dolphins and other predators
Bull sharks (pictured) are one of the most-feared of all shark species, mainly because they prey in the shallows, around estuaries and even miles upstream in rivers, which means they are more likely to come into contact with humans. However, off Santa Lucia on Cuba’s northeastern shore, between August and February, divers can view these awesome predators at close range, as a local dive centre routinely hand-feeds them with scraps of fish.
8/10 Canary Islands, Spain
The Canary Islands, a sun-and-sand tourist hotspot, might seem an unlikely place for shark diving, but there is a species of shark that resides in these waters. The angel shark (pictured) is a placid, bottom-dwelling animal that closely resembles a ray at first glance. Growing up to two-and-a-half metres in length, they are hard to spot, often lying camouflaged on the seabed.
9/10 Galapagos Islands, Ecuador
The world-famous Galapagos Islands, an archipelago of volcanic islands sitting astride the Equator some 575 miles from the Ecuador coastline, have been in the top five best dive destinations on the planet ever since liveaboards started visiting here. Divers can expect up close and personal encounters with scalloped hammerhead sharks (pictured), Galapagos sharks, and even mighty whalesharks.
10/10 Cocos Islands, Costa Rica
The remote Cocos Islands - they lie some 340 miles off the coast of Costa Rica - are a magnet for divers seeking some serious shark action. Designated a UNESCO World Heritage Site in 1997, Cocos boasts various species of shark in its waters, but is most renowned for its massive shoals of scalloped hammerheads and whitetip reef sharks (pictured).
