Beautiful patterned shell 10-15 cm long. The most venomous of all cone snails. Hunts fish with a venomous harpoon-like tooth fired from a proboscis.

Conotoxin causes total paralysis with no antidote — mortality ~30%. Victims describe being conscious but unable to move or breathe. Patients survived by being put on ventilators until toxin cleared.

Coral reefs and sandy areas of tropical Indo-Pacific — Australia, PNG, Indonesia, Philippines, all Pacific islands.

Slow-moving but hunts fish (!) by harpooning them with a tooth shot at high speed. Tourists picking up the pretty shell get stung.

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

Hemotoxic venom causes severe local damage, hemorrhage, hypotension. About 200 bites/year in Israel. Mortality <1% with antivenom; previously 5-7%.

Mediterranean coastal regions of Israel, Lebanon, Syria, Jordan, southern Turkey. Coastal plains, forest edges, agricultural land.

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

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.

Cousin of saw-scaled viper, up to 75 cm. Sandy-grey with darker pattern. Causes most snakebites in the Arabian Peninsula and Israel's southern deserts.

Hemotoxin causes severe bleeding, kidney failure. Highly aggressive — strikes repeatedly. Number one cause of snakebite death in Saudi Arabia, Oman, Yemen, UAE, southern Israel.

Rocky deserts and mountain wadis of Saudi Arabia, Yemen, Oman, UAE, southern Israel, Jordan, southern Egypt.

Nocturnal in summer. Makes 'sizzling' warning sound by rubbing scales — same as African saw-scaled. Easily overlooked due to camouflage.

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.

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.

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.

Sting causes intense burning pain, blistering, scarring lasting weeks. Allergic reactions can cause anaphylaxis. Closes beaches across Spain, France, Italy in summer.

Small sandy-brown fish — up to 15 cm — that buries itself in shallow sand with only its eyes and dorsal spine showing. Found at swimming depth.

Powerful bite that won't let go. Serrated teeth cause ragged wounds; saliva carries bacteria causing severe infection. Numerous diver injuries each year.

Rocky reefs and shipwrecks of the Mediterranean Sea down to 80 m depth.

Ambush predator. Hunts at night for fish, octopus, and crustaceans. Aggressive when its hole is approached or when fed by divers.
