Small (50-90 cm), sandy-coloured viper with serrated scales that rasp together producing a warning sound. Despite size, considered the world's deadliest snake by total kill count.

Estimated to cause 20,000+ deaths annually across its range — more than any other snake. Hemotoxin causes uncontrolled bleeding. Highly aggressive — strikes without provocation.

Dry regions from West Africa across Middle East to India, Pakistan, Sri Lanka. Sand, scrub, rocky desert.

Nocturnal. Makes a distinctive 'sizzling' sound by rubbing serrated scales — a warning. Strikes faster than human reflexes — multiple times per second.

Small, dark tick — the primary disease vector in Europe. Despite being only 3–4 mm, kills more Europeans annually than any other animal.

Transmits Lyme borreliosis (200,000+ cases/year), tick-borne encephalitis (3,500+ cases/year, ~30 deaths), babesiosis, anaplasmosis. The TBE vaccine exists.

Forests, parks, tall grass, urban green spaces. Most active April–June and September–October.

Quests on grass tips and twigs, latching on contact. Seeks warm, moist body sites. Feeds for 3–7 days before dropping off.

Largest land predator in Europe. Males reach 350 kg. Mostly omnivorous; can outrun a horse over short distances and is an excellent swimmer and tree-climber when young.

Attacks rare but documented — about 10 fatal attacks per decade across Europe. Most occur when surprising a sow with cubs or a wounded individual.

Mountain forests of the Carpathians, Scandinavia, Balkans, Pyrenees, Alps, and Russian taiga.

Hibernates Nov–Mar in dens. Active at dawn and dusk. A sow defending cubs is the most dangerous scenario.

Common throughout Europe. Males reach 200 kg with razor-sharp tusks. Adapts well to humans — boars now roam parks of Berlin, Rome, and Barcelona; 3,000+ in Berlin alone.

Causes more wild-animal injuries in Europe than any predator. A sow defending piglets or a wounded male can disembowel within seconds.

Forests, fields, and increasingly suburban areas of major cities.

Lives in family groups (sounders). Active at dusk and night. Charges with tusks aimed at the legs and groin — capable of 40 km/h.

Grey or brown with a distinctive zigzag along the back, up to 80 cm. The northernmost venomous snake in the world — found inside the Arctic Circle in Lapland.

Hemotoxin causes pain and swelling. Around 0.5% of bites are fatal — usually only in children, the elderly, or those with allergies. About 7,500 bites per year across Europe.

Forests, bogs, heathland, and mountain meadows up to 3,000 m elevation.

Shy and retreating. Bites only when stepped on or cornered. Active by day in cool weather, by night in summer.

Striking red-orange viper with black zigzag, up to 70 cm. Endemic to the Western Caucasus. Critically endangered due to poaching for venom trade.

Most potent viper venom in former USSR territory. Hemotoxic — causes severe local damage, hemorrhage, possible kidney failure. Antivenom limited.

Endemic to the Western Caucasus — mountain forests and meadows of Georgia, Russia (Krasnodar Krai), northeast Turkey.

Diurnal. Hibernates 6 months in mountains. Found at 100–2000m elevation. Females give live birth — 4-12 offspring.

Yellow-brown scorpion 4-5 cm with dark stripes. The most widespread scorpion in Central Asia and the Caucasus — found from Turkey to China.

Venom is much less potent than Centruroides or Androctonus. Stings cause intense pain, swelling, burning, occasionally numbness. Rarely life-threatening to healthy adults — but children and allergics at risk.

Arid steppes and semi-deserts of Caucasus (Armenia, Azerbaijan, Georgia), Iran, Afghanistan, Pakistan, Turkmenistan, Uzbekistan, Tajikistan, Kyrgyzstan, Kazakhstan, southern Mongolia, northern China.

Nocturnal. Doesn't dig burrows — uses natural cracks and spaces under stones. Active spring–autumn. Hibernates in winter.

European wolf, smaller than its Russian or American cousins. Returning to Western Europe after centuries of absence — first wolves in Belgium since 1900 arrived in 2018.

Healthy wolves almost never attack humans — only 0–2 fatal attacks per decade in Europe. The real risk is rabid individuals; rabies is now mostly eliminated in Western Europe.

Forests and mountains of Eastern Europe, Scandinavia, the Balkans, and increasingly Germany, France, Belgium, and the Alps.

Hunts in packs. Highly intelligent and avoids humans. Communicates by howling over distances of 10 km.
