Species Facts

Dermochelys coriacea

Leatherback sea turtles can dive deeper than 1,000 metres and travel over 10,000 km between feeding and nesting grounds.

Carcharodon carcharias

Great white sharks can detect a single drop of blood in 100 litres of water and sense electrical fields produced by other animals.

Physeter macrocephalus

Sperm whales have the largest brain of any animal that has ever lived on Earth, weighing up to 9 kg.

Ginglymostoma cirratum

Nurse sharks are one of the few shark species that can rest motionless on the seafloor — they pump water over their gills rather than relying on forward motion to breathe.

Stenella coeruleoalba

Striped dolphins can leap up to 7 metres out of the water and are capable of swimming at speeds exceeding 25 km/h.

Coral reefs support around 25% of all marine species despite covering less than 1% of the ocean floor.

Jellyfish have no brain, no heart, and no bones — yet they have survived five mass extinction events.

By 2050, there could be more plastic in the ocean by weight than fish, if current trends continue.

Seagrass meadows can capture carbon up to 35 times faster than tropical rainforests, making them vital allies in the fight against climate change.

A humpback whale weighing 30 tonnes can launch itself almost entirely out of the water — an extraordinary feat of power requiring enormous muscular effort.

Sea turtles use the Earth's magnetic field as a GPS system, detecting both field intensity and inclination angle to navigate across thousands of kilometres of open ocean.

Mobula birostris

Manta rays have the largest brain-to-body ratio of any fish species and have been observed apparently recognising their own reflection.

Hippocampus sp.

Seahorses are the only species on Earth where the male carries and gives birth to the young — a male can give birth to up to 2,000 young in a single pregnancy.

A single Seabin device can collect up to 1.5 kg of floating debris per day, including microplastics as small as 2mm.

Sunlight can only penetrate to approximately 200 metres in the clearest ocean water — below this depth, the ocean is in permanent twilight or darkness.

Cuttlefish have around 10 million colour-changing cells called chromatophores in their skin — yet they are completely colour-blind, navigating colour through polarised light.

An estimated 76% of deep-sea marine species are bioluminescent — making it the most common form of communication in the ocean.

The ocean has become 26% more acidic since the Industrial Revolution — a rate of change faster than anything seen in the past 300 million years.

Humans kill approximately 100 million sharks every year. Sharks kill an average of 10 humans. The real danger runs in one direction only.

Megaptera novaeangliae

Blue whale calls can travel thousands of kilometres through the ocean — making them the loudest animals on Earth, producing sounds up to 188 decibels.

Octopus vulgaris

Two-thirds of an octopus's neurons are in its arms, not its brain — each arm can taste, touch, and make decisions independently.

Well-managed Marine Protected Areas can increase fish biomass by up to 600% — and the benefits spill over into surrounding unprotected waters.

Chelonia mydas

Green sea turtles are the ocean's lawnmowers — their grazing keeps seagrass beds short and healthy, increasing productivity and providing habitat for hundreds of other species.

Physeter macrocephalus

Sperm whale clans have distinct click dialects passed down through generations — a form of cultural identity unique among non-human animals.

Eretmochelys imbricata

Hawksbill turtles eat sea sponges that are toxic to almost every other animal — and by doing so, they prevent sponges from smothering coral reefs.

Tursiops truncatus

Dolphins can detect a golf ball-sized object at 100 metres using echolocation — and can 'see' inside other animals, detecting pregnancy and internal injuries.

There are now over 700 ocean dead zones worldwide — and they are growing. The Gulf of Mexico dead zone alone covers an area larger than Wales.

Enhydra lutris

Sea otters wrap themselves in kelp to anchor themselves while sleeping — and in doing so, they protect the very ecosystem that keeps them alive.

Rhincodon typus

The whale shark is the largest fish in the ocean — yet it feeds on some of the smallest organisms, filtering over 6,000 litres of water per hour.

During coral spawning, a single reef can release billions of egg-sperm bundles in a single night — the ocean turns pink with the density of reproductive material.

Dermochelys coriacea

Only around one in a thousand leatherback hatchlings will survive to adulthood — making every individual that reaches the sea critically important to the species.

The ocean conveyor belt moves water around the entire planet in a cycle that takes approximately 1,000 years — and it keeps Western Europe up to 10°C warmer than it would otherwise be.
