Habitat & Geographic Range

Горбатый кит

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 11 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (5 countries), and South America (Colombia, Ecuador, Venezuela). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Pondskater

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.

Common Pondskater

<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.
