Habitat & Geographic Range

cobweb spiders

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).

Gorila Occidental

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical grasslands and savannas, and flooded grasslands and savannas, among 4 distinct biome types within the Afrotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Cameroon, Congo (Republic), Equatorial Guinea, and Gabon. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

cobweb spiders

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.

Gorila Occidental

El primate más grande del mundo, los gorilas occidentales pesan hasta 180 kg y habitan los bosques tropicales y subtropicales del África ecuatorial. Principalmente herbívoros, viven en grupos familiares liderados por un macho de espalda plateada que protege la tropa y media en los conflictos sociales. En Peligro Crítico, con poblaciones amenazadas por la deforestación, la caza furtiva para la venta de carne de monte y los brotes del virus del Ébola.
