Up to 1.3 m. Grey-brown with darker zigzag. Israel's national reptile and main cause of envenomation in the Levant.

Crepuscular in summer. Often found in cultivated areas. Strikes when threatened — quick to defend itself.

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.

Glossy black with 13 red spots on the back — hence its Italian name, malmignatte. Smaller than American black widow but with similar venom.

Alpha-latrotoxin causes severe muscle spasms, abdominal cramping, hypertension, and sweating ('latrodectism'). Antivenom available; before its development, mortality was 4–5%.

Dry steppes, vineyards, abandoned buildings, and stone piles across southern Europe and the Balkans.

Builds tangled webs near the ground. Female bites only when pressed against skin — typically when moving rocks or harvesting grapes.

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.

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.

Light brown spider 7-10 mm with a violin-shaped marking on the head. Six eyes (most spiders have eight). Increasingly common in southern European homes.

Cytotoxic venom causes 'loxoscelism' — necrotic skin lesions that can rot for weeks. Confirmed deaths in Italy and Spain in recent years.

Walls, attics, woodpiles, behind furniture in homes across Italy, Spain, Portugal, southern France, Greece, Croatia, Cyprus, Malta.

Reclusive — bites only when pressed against skin (e.g., in clothes or bedding). Active at night hunting other arthropods.

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, up to 8 cm. Found in Spain, southern France, Italy, the Balkans. The largest scorpion in Europe.
