Fish could be more intelligent than we've given them credit for in light of new footage that shows grouper coral working with an octopus to catch their prey. Their remarkable interactions were captured during a shoot for BBC One's Blue Planet II and will be shown on TV for the first time tomorrow night.

Footage from episode three of Blue Planet II shows a grouper coral fish (left) team up with an octopus to catch its prey Their solution sees the grouper fish chase the smaller ones into a crevice and then turn a paler color to attract the octopus attention.

Viewers will be able to witness the impressive partnership for themselves on tomorrow night's 'Reef' episode of Blue Planet. Sir David, who narrates the series, told The Telegraph: 'The fish takes fright and swims straight into the grouper's jaws.

Dr Alex View, a Cambridge University scientist turned cameraman, who was behind the amazing footage told the newspaper: 'When I first saw it, I was blown away. The episode's producer Jonathan Smith commented: 'What we discovered is that this fish is capable of forward planning and cooperatively hunting with a completely unrelated animal, in this case an octopus.

Another amazing bit of team work filmed for this week's episode is when a shoal of bream come together to get rid of some sand covering up a dangerous Bobbie worm. Usually the erelong creatures lie low before sucking fish to the ocean floor, but the breams' handiwork means they can expose them before it's too late and avoid their deadly jaws.

Clownfish are also filmed off the coast of Borneo moving a coconut shell near their anemone so the female can lay eggs there. Octopus and fish join forces to hunt prey in filming first for blue planet ii.

The astonishing partnership was captured for the first time by filmmakers shooting on the Great Barrier Reef for BBC Blue Planet II. After chasing a fish into a crevice, it turns slightly paler to attract the octopus attention, before standing on its head and wiggling its tail to signal that a meal is hiding in the hole.

The grouper first spots where the little fish has hidden then informs the octopus Credit: BBC For its part, the octopus pokes its long, thin tentacles into the crevice, flushing out the prey.

Sir David Attenborough, who narrates the series said: “The fish takes fright and swims straight into the grouper ’s jaws. Scientists now think the partnership between the grouper and octopus, which involves rudimentary sign language, shows intelligence which could rival that of crows or even chimpanzees, our closest relative.

Jonathan Smith, producer of ‘Reef’ said: “What we discovered is that this fish is capable of forward planning and cooperatively hunting with a completely unrelated animal, in this case an octopus. “He puts his head down, flashes white, wiggles in front of the octopus and gets its attention.

Other astonishing collaborations filmed for the episode include a small shoal of bream coming together to blow away sand covering a dangerous meter long Bobbie worm, which lies in wait to snatch fish and suck them under the ocean floor. The new episode has also recorded the dawn chorus of sea creatures as they awaken in the morning, as well as a turtle lying back to enjoy a ‘spa’ treatment from hundreds of cleaner fish.

Reefs are one of the most competitive areas to live in the ocean so to get ahead you've got to come up with these ingenious techniques.” After watching them for 30 seconds or so, I swam over and took a couple photos before the grouper got nervous and left.

# of Dives: 500 – 999 Location: Silicon Valley, CA / New Bedford, MA / Kira, Maui The bottom photo is closest to the true colors, the top photo is fairly close but a little desaturated. The photos were from 15' away, 30' depth, available light only, auto WB (no manual white balance on my point and shoot).

Peacock groupers are pretty skittish and don't like to hang around for closeups, so I had to shoot with 3x telephoto and then crop. From my experience, groupers as well as other fish will follow an octopus to pick up free food scraps.

The peacock grouper along with the blue goat fish and trumpet fish will also follow. It's the best time to video or photograph them due to their preoccupation with a free meal.

If you see an octopus propped up on a rock (almost standing if they could) that means it is eating, most likely a crab. # of Dives: Location: Kabuki, Oahu, Hawaii In fact, the first picture you posted shows the octopus up on it legs.

If this was one of the first shots then yes, I bet there is a crab within the clutches of its beak, and therefore that makes sense why the grouper would leave when you showed up! # of Dives: 1,000 – 2,499 Location: Eagle River, Alaska moved to Cape Cod, Mass Scuba Drew; Nice website.

I've been followed by trumpet fish at night (in Oahu) as I shone my light on creatures. When the small fishes dart out of their hiding spot, they are chased straight into the grouper's mouth.

However, in some instances, in which the researchers observed twice, the octopus lashes out even if it is not going to get the prey, but the team are unsure what the purpose is. (Image: GETTY)”In the first one, benefits are disregarded entirely by the octopus, and punching is a spiteful behavior, used to impose a cost on the fish.

“In the other theoretical scenario, punching may be a form of aggression with delayed benefits (i.e. direct negative reciprocity or punishment), where the octopus pays a small cost to impose a heavier one on the misbehaving partner, in an effort to promote collaborative behavior in the following interactions.” Marine biologist Eduardo Sampan from the University of Lisbon in Portugal described it as “probably the most fun I had writing a paper”.

But the coral grouper not only seeks out giant morays, but actively rouses them by vigorously shaking its body. The grouper ’s bursts of speed make it deadly in open water, while the moray’s sinuous body can flush out prey in cracks and crevices.

He also took several films and when Alexander View from the University of Cambridge watched them, he noticed something Share had missed. Most morays and all wrasses headed towards the grouper ’s location when they saw the signal, causing the prey to break their cover.

(The fact that the prey didn’t abandon their hiding spots beforehand shows that the headstand itself isn’t a hunting tactic.) And when the morays ignored the headstand, the groupers actually swum after their partner and either performed their “recruitment shimmy” or forcibly tried to push the eels in the right direction.

Such gestures are part and parcel of human life, but the only animals that seem to use them are intelligent ones, like chimps and other great apes, ravens, dolphins, and domestic dogs. Good For You is a body of work highlighting the unexpected symbiotic relationships found in nature.

As an artist, I am continually drawn to the mysterious aspects of our natural world. I seek to understand our natural environments better, and to share these beautiful realities with others.

It seems that there are infinite lessons to be learned from the way that chemicals, bacteria, species, and ecosystems, interact. In an era where mankind feels fractured, I have found comfort in the natural and beneficial relationships between species in all types of environments.

I have fused two personal artistic styles, allowing familiar creatures to be seen in a new way. I seek to demonstrate the seen and unseen efforts and benefits that come from working interdependently with the planet and one another.

Learning more about our natural world allows us to know and love the incredible earth we have more deeply, and care for it more fully. This signals the plover to enter, and they clean their teeth by picking off food remains which prevents infection.

The bird gets a good meal and the crocodile remains dentally hygienic and healthy. Their secondary function is that the bird easily senses danger and let's out warning cry’s that signal the crocodiles dash into the safety of the river where they disappear.

They keep the shark healthy, and in return they are offered meals, protection, and transportation through the vast arts of the ocean. During the day the clownfish will search for food near the sea anemone, and at night return to cuddle in its tentacles.

According to National Geographic, new discoveries show that the clownfish also fertilizes the anemone with its waste. Clownfish remain active during the night, allowing water to flow through the tentacles and for the anemone to receive oxygen and nutrients that are critical to its health and growth.

John Zaeschmar plans to write two publications from the data collected during the Blue Planet II shoot. Over time, in certain parts of the deep, this organic matter becomes compressed into sub-surface pockets of methane gas.

Observations during filming of Blue Planet II in the Gulf of Mexico will lead to two potential papers: one which will report the deep (>500 m water depth) water temperature trends in the Gulf of Mexico deep which look to be increasing and another, which models the temperature data to predict the stability of methane deposits on the seafloor. If stability decreases this could have wide scale implications for our climate and the animals that live in the deep sea.

The expedition's footage will help us to understand how seafloor slopes and car-sized boulders dropped by passing icebergs influence the pattern of life on the deep ocean floor around Antarctica Grouper use the fish equivalent of sign language, dubbed the ‘headstand signal’, to reach across the vertebrate-invertebrate divide and encourage another species to help it hunt.

Until now, this kind of gesturing behavior has been associated mainly with apes and birds in the crow family, such as ravens, but several species of Groupers are now known to ‘point’. This was expanded on in 2013 by Dr Alexander View who described the communication and signalizing behavior between Grouper and Reef Octopus.

In Great Barrier Reef, Australia, Bobbie Worms are large ambush predators which lie in wait in the sand and attack passing prey. Monocle Breams have figured out how to mob the Bobbie Worm by blowing water on their exposed jaws.

Saddle back Clownfish live out in the open sand in Borneo away from the reef and have no hard material to lay their eggs on. The unique aspect of this behavior is that these Clownfish actively finds pieces of material to lay their eggs on.

These tenacious fish will move objects many times their size from plastic bottles to coconut shells. Dr Alexander View and colleagues plan to publish a paper showing that these little hoarders push objects many times their own body weight meters to their anemones, and have very specific tastes of what makes a good home for their unhatched babies.

The behavior was scientifically described for this first time in Guy’s PhD thesis published early this year (2017). Footage captured by Blue Planet II demonstrates definitively that Mobile Rays are capable of targeting schools of fish and this will form the basis of a scientific note written by Joshua Stewart.

Story of older Wandering Albatross caring more for their last chicks was studied by Hannah From in 2013. Female Cuttlefish display a white stripe to signal their intention to reject a mating attempt.

The Pacific Leaping Benny is thought to be even more land-based then the mud skipper but it still needs to keep its skin moisturized and often feeds on algae near to the surf zone. To avoid being swept off the rocks into the surf zone the Benny can leap a number of times its body length.

We used Canon and Sony cameras to film Noctilucent ‘sea sparkles’ glowing at night, around the wing beats of shoaling Mobile Rays, as they gather off the Mexican coast. The result is a magical experience, with rays swooping around the camera, glowing sparkles trailing in their wakes.

Collaborating with Gates housings, the team built a huge, domed port, 24 inches across, allowing us to gain perfect focus and exposure, both above and below the waterline. The team, working with in-house designer Moran Sadhu x built a ‘mo-co’ rig, used to great effect, to film a rock pool in time-lapse.

As the tides rose and fell around it, the rig would keep filming, its steady tracking time-lapse allowing us to reveal the underwater life of a rock pool like never before. The team built camera to be towed behind a boat, allowing us to film fast-moving Yellow fin Tuna and huge shoals of Spinner Dolphins, as they travel at speed through the Open Ocean.

Beating their cloak-like wings as they feed, Mobile Rays stir up plankton, some of which produces bioluminescence when disturbed. Working from science and exploration vessel the Lucia, the Deep team and scientists mounted an expedition off the central coast of Chile to film Humboldt squid from a submersible.

But its sediment, made from organic matter fallen from the surface over millennia can become compressed into pockets of methane gas. For the very first time, the Deep team has filmed violent eruptions of bubbles of gas the size of basketballs, shooting out of the seabed almost a half-mile down.

The male and female shrimp enter the Venus Flower Basket sponge when they are small, but eventually become too big to get out. Grouper use the fish equivalent of sign language to reach across the vertebrate-invertebrate divide and encourage another species to help them hunt.

Mobile Rays and Spinner Dolphins feed on Lantern fish forming a huge, dense bait ball at the surface. The Octopus grabs shells and rocks in its suckers and uses them as body armor as a camouflage and physical defense strategy against predators like sharks.

The Pacific Leaping Benny, thought to be even more land-based then the mud skipper, spends its days on the rocky shore. By flashing an orange patch on its dorsal fin, the male attracts a female to his nest in the rock crevice.

Sea lions work together to hunt tuna in a labyrinth of small bays in the Galápagos Islands- a behavior not filmed professionally until Blue Planet II.
