A smaller, sneaky male uses subterfuge, even pretending to be a female, to confuse rivals and get his girl. But even among these giant cuttlefish, the largest of their kind, it's not always size that counts. Soft-bodied and weakened, they must avoid the patrolling four-metre-long stingrays.įurther along the coast, the greatest gathering of cuttlefish in the world takes place, as males battle it out for the right to mate. The army marches into the shallows and starts to pile one on top of each other, building mounds over a metre high. With the first full moon of winter, strange creatures emerge from the deep - spider crabs. Once a year, one sea meadow in Australia is overrun by an extraordinary invasion. In this way, sharks have become surprising allies in the fight against climate change - as a patch of sea grass is 35 times more efficient at absorbing and storing carbon than the same area of rainforest. By keeping turtles on the move, tiger sharks prevent the seagrass meadows from being overgrazed. Here, grazing green turtles are stalked by tiger sharks. Off Western Australia, vast prairies of seagrass extend to the horizon. In warmer waters another green sea takes hold. In a filming first, we reveal great rafts of sea otters now numbering in their hundreds. Today, thanks to protection, sea otter numbers are recovering, along with the health of the forest. And with them gone, urchin numbers rose, destroying many forests. Back in the late 1800s, sea otters were hunted for their thick pelts to near extinction. All is not entirely lost, thanks to the return of a ravenous forest resident - sea otters. But urchins can swarm in vast numbers and even attack and fell the kelp forest itself, creating vast 'urchin barrens'. When spiny urchins invade and graze their crops, the Garibaldi desperately pick them off. In clearings, bright orange male Garibaldi fish guard territories of short turf seaweed. To outwit her nemesis, the pyjama shark, she uses ingenious tactics, never filmed before.Īlong the Pacific coast of North America stand, at 60 metres high, the largest and perhaps most diverse kelp forests in the world. Almost a hundred different species of shark patrol these waters, driving one resident - the common octopus - to become the ultimate escape artist. The most bountiful kelp forests are found off the tip of southern Africa, where two great oceans collide. They are the most abundant but fiercely competitive places in the ocean to live. Here sunlight powers the growth of enchanted forests of kelp, mangroves and prairies of sea grass. It's our green seas, not the blue, that bring life to our oceans.

They spent 6,000+ hours diving underwater, filming everywhere from familiar shores to the deepest seas. Over 4 years in production, the “Planet Earth: Blue Planet II” teams mounted 125 expeditions, visited 39 countries, and filmed on every continent and across every ocean. It reveals astonishing characters, otherworldly places and extraordinary new animal behaviors. The series uses breakthroughs in science and cutting-edge technology to explore this final frontier. Our final frontier is the deep ocean – Earth's “inner space.” There is more life in the deep sea than anywhere else on Earth, and it’s said we know more about the surface of Mars than the depths of our own planet. They cover 70% of the Earth’s surface and hold 97% of all the water in the world. Presented by Sir David Attenborough and scored by Academy Award-winner Hans Zimmer, “Planet Earth: Blue Planet II” takes viewers on a revelatory and magical journey into the mesmerizing world of our oceans - by turn tempestuous and serene, exquisitely beautiful and bleakly forbidding.
