Habitat & Geographic Range

Gepard

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 9 distinct biome types spanning the Afrotropic and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Botswana, Iran, Kenya, Namibia, and Tanzania. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Gemeiner Wasserläufer

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Gepard

The fastest land animal on Earth, reaching speeds of 112 km/h over short distances across African and Iranian grasslands. Slender build with a deep chest, long legs, and distinctive black tear-stripe markings. Unlike other big cats, cheetahs vocalize with chirps and purrs. Vulnerable, with only ~7,000 remaining due to habitat fragmentation and competition with larger predators.

Gemeiner Wasserläufer

<em>Gerris lacustris</em>, the common pondskater, is an aquatic insect in the family Gerridae, well known for its remarkable ability to walk and skate across the surface of still or slow-moving freshwater bodies using surface tension. Microscopic water-repellent hairs on its legs trap air and prevent the insect from breaking the water film, allowing it to detect vibrations from struggling prey and move rapidly across the water surface. The species is a predator and scavenger, typically feeding on small invertebrates, including other insects, that fall onto or become trapped at the water surface. <em>Gerris lacustris</em> is distributed across Europe, with confirmed records from Belgium, Denmark, Norway, and Sweden, and is among the most commonly encountered water striders in temperate European ponds, lakes, and slow-flowing rivers. It is assessed as Least Concern on the IUCN Red List, reflecting widespread abundance and absence of major conservation threats. The species overwinters as an adult in terrestrial habitats and returns to water in spring. Biological traits such as average adult lifespan, precise body dimensions, body mass, and detailed dietary composition remain poorly documented in the scientific literature. Adults are capable of flight and can colonise new water bodies effectively.
