Largest land carnivore on Earth — males up to 800 kg. In Europe found only in Norway (Svalbard) and the Russian Arctic.

The only bear that actively hunts humans as prey. Hungry bears, increasingly common with shrinking ice, are extremely dangerous. On Svalbard, carrying a rifle outside settlements is mandatory.

Arctic ice and coast — Svalbard, Franz Josef Land, Greenland, northern Russia.

Solitary. Travels enormous distances on sea ice hunting seals. Will stalk humans for hours before striking.

World's largest jellyfish — bell up to 2 m wide, tentacles up to 30 m long. Russet-brown 'mane' of dense tentacles. Drifts on Atlantic currents to Britain and Ireland.

Sting causes severe burning pain, blistering, and in rare cases anaphylaxis or heart problems. Beach closures in Ireland, UK, and Norway each summer.

Cold waters of the North Atlantic — Norway, Iceland, UK, Ireland, Baltic. Drifts south in late summer.

Slow drifter — moved by currents and tides. Can sting through thin clothing. Even detached tentacles remain dangerous.

Largest dolphin — up to 9 m and 6 tons. Apex predator of the oceans. Since 2020, a pod off Iberia has been deliberately ramming and sinking sailboats.

No fatal attacks on humans in the wild ever recorded — but as of 2024, over 700 boat ramming incidents and 4 sailboats sunk off Spain and Portugal. Direct human risk: drowning during shipwreck.

All European waters — Atlantic, Bay of Biscay, Mediterranean (rare), Norwegian Sea, North Sea. Iberian pod active off Spain, Portugal.

Highly intelligent, social — pods of 5-30. Teach each other behaviours culturally. The boat-ramming is being learned by new generations.
