Deep-sea facts and ocean wonders
Humpback whales sing complex songs that can travel thousands of kilometres through the ocean. Scientists believe these songs are used to attract mates and communicate with other whales.
Starfish can regrow lost arms, and some species can even grow an entirely new body from just one arm. This remarkable ability is called regeneration.
The deep-sea anglerfish dangles a bioluminescent lure from its head to attract prey in the pitch-black ocean depths. When an unsuspecting animal approaches the light, the anglerfish snaps it up with its enormous jaws.
Ocean tides are caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The highest tides in the world occur in the Bay of Fundy in Canada, where water levels can rise by up to 16 metres.
Seahorses are the only animal species where the male carries the babies. The female deposits her eggs into a pouch on the male's belly, and he gives birth to hundreds of tiny seahorses.
The ocean is never truly still — currents, tides, and waves keep water moving constantly around the globe. A 'conveyor belt' of deep ocean currents circulates water around the entire planet over about 1,000 years.
The mantis shrimp can punch with the speed of a bullet, striking so fast that it creates a flash of light and a shockwave that stuns or kills its prey. It has the most complex eyes of any animal, able to see colours humans cannot.
Flying fish can launch themselves out of the water and glide through the air for up to 200 metres using their wing-like pectoral fins. They reach speeds of up to 70 kilometres per hour during their aerial glides.
The nautilus has barely changed in 500 million years, making it a living fossil. Its beautiful spiral shell follows a mathematical pattern known as the golden ratio.
Around 76% of deep-sea creatures are bioluminescent, meaning they can produce their own light through chemical reactions. This light is used to attract prey, find mates, and confuse predators.
