Ragged-tooth sharks might look ferocious with their rows of razor sharp teeth but these creatures are surprisingly docile and are happy to share the water with curious divers. In this week's episode our cameraman travels to Aliwal Shoal, South Africa for some very close encounters with these amazing sharks.

The annual Sardine Run phenomenon brings huge shoals of migrating sardines past South Africa’s eastern coastline – and baitballs of these bite-sized fish don’t stand a chance against the ocean’s top predators. From the bizarre-looking garfish to the large Zambezi shark, the predators waste no time getting in on the feeding action, and the tiny anchovies are attacked from every direction. It’s a breathtaking experience for our cameraman – but it’s not without risk! During a few hair-raising moments, the panicked fish attempt to use him as cover from the frenzied blacktip reef sharks.

Our cameraman films a pair of mating leopard sharks and a cuttlefish laying her eggs. There’s also a rare glimpse of a tiger-tail seahorse and some bizarre pufferfish behaviour.

Divers in Indonesia’s Cenderawasih Bay are almost guaranteed a sighting of whale sharks. Well-known to the locals, these gentle giants gather in huge numbers around fishing platforms waiting for an easy meal. We’re treated to an amazing and close-up encounter with these ocean behemoths as they gulp down mouthfuls of small fish.

Exploring the waters off Thailand’s picturesque Koh Racha Noi island is like diving in an aquarium! A powder blue surgeon fish darts past, redtail butterflyfish school above the reef and a peacock mantis shrimp scuttles across the coral, showcasing its extraordinary colourations. We’re also treated to a pufferfish feeding display and a close-up look at the beautiful bearded scorpionfish – all in ultra HD.

Filming the notoriously fierce and territorial titan triggerfish calls for extra caution this week. Our final dive from the Philippines also brings us a rare sighting of a critically endangered green turtle and a lucky encounter with a beautiful clown triggerfish – all in ultra-HD!

It’s all about the eels this week … in ultra-HD! A fimbriated moray eel hides out in a crevice, while a white-eyed moray puts on a stunning and rare display as it swims across the reef on the hunt for dinner. We’re also treated to a close-up encounter with a creepy-looking burrowing sea cucumber and an unusual starfish!

In this week’s Wild Oceans, we explore the untouched reefs of the Philippines in ultra high definition. A beautiful lionfish shows off its venomous spines, tiny shrimp scuttle across an anemone, and we take a close-up look at a vividly coloured nudibranch. There’s even a ‘mystery fish’ that has our seasoned underwater cameraman scratching his head. Can you identify it? Let us know in the comments below!

A close encounter with a cruising hawksbill turtle, a huge school of swarming catfish, a bizarre-looking giant frogfish ‘hopping’ across the corals and pristine reefs as far as the eye can see! This World Oceans Day, we celebrate the wonders of the underwater world in ultra high definition with another extraordinary dive in Sogod Bay, Philippines.

Filming in 4K, cameraman Stewart Whitfield takes us on a wall dive at Sogod Bay in southern Philippines. The beauty of this dive lies in the incredible quality of the reef and the extraordinary details and colours this camera can capture. Look out for damselfish, masked porcupine pufferfish, a magnificently camouflaged spiny devilfish and even some soft corals filmed in high speed. Special thanks to www.rayadivers.com

Our underwater cameraman gets a good workout keeping up with an eagle ray on the hunt for its next meal. With their large wingspans and long whiplike tails (which are barbed with venomous spines!), these beautiful creatures are able to glide effortlessly through the water – so getting good shots of them can be tricky! And that’s not the only ray to make an appearance this week: keep an eye out for the stunning (and far less camera-shy) round ribbon-tail ray.
