Habitat & Geographic Range

Amerikanische Schwarze Witwe

Habitat

Typically found in terrestrial habitats from forests to deserts.

Range

Widely distributed across Asia (Japan), Europe (8 countries), North America (United States), and South America (Ecuador).

Giraffe

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Amerikanische Schwarze Witwe

The southern black widow (Latrodectus mactans) is one of North America's most recognizable and medically significant spiders, a member of the genus Latrodectus within the family Theridiidae. Females are glossy black with the iconic red hourglass marking on the underside of the abdomen, and reach approximately 8–15 millimeters in body length; males are smaller, paler, and largely harmless. The species constructs irregular, low-lying cobwebs in dark, sheltered locations including woodpiles, outbuildings, hollow logs, rock piles, and debris, where it waits for prey—primarily insects—to blunder into the sticky tangle. Distribution spans the southeastern United States westward through Texas and northward into more temperate zones, with range overlap with related widow species. The venom of Latrodectus mactans contains alpha-latrotoxin, a potent neurotoxin that triggers massive release of neurotransmitters at synaptic junctions, causing the syndrome of latrodectism: severe muscle cramps, pain, hypertension, and autonomic disturbances. Despite its fearsome reputation, bites are rarely fatal in healthy adults when medical treatment is available. Females are cannibalistic toward males, though this behavior is less consistent in nature than laboratory conditions suggest. The species plays an important ecological role in controlling insect populations in arid and semi-arid habitats. Its conservation status has not been formally evaluated by the IUCN.

Giraffe

The tallest living animal on Earth, giraffes can reach 5.5 meters in height and weigh up to 1,750 kg. Their elongated necks — containing the same seven cervical vertebrae as all mammals — evolved for feeding on acacia trees in African savannas and woodlands. Social animals living in loose herds with no permanent bonds, giraffes communicate through infrasound and body language. Vulnerable, with populations declining due to habitat loss and poaching.
