Habitat & Geographic Range

Ballena azul

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 (4 countries), and South America (Colombia, Ecuador). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Clubbed General

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden. Listed as Near Threatened, this species requires ongoing monitoring to prevent population decline.

Ballena azul

El animal más grande que se conoce haya vivido en la Tierra; las ballenas azules pueden alcanzar 33 metros y 200 toneladas — sus corazones solos pesan tanto como un automóvil pequeño. Se encuentran en todos los océanos y migran entre las zonas de alimentación polares y las áreas de reproducción tropicales. Son filtradoras que consumen hasta 4 toneladas de kril al día. En peligro de extinción, con poblaciones globales estimadas entre 10.000 y 25.000 tras casi extinguirse por la caza de ballenas en el siglo XX.

Clubbed General

Stratiomys chamaeleon is a soldier fly in the family Stratiomyidae, commonly known as the clubbed general. It is a large, distinctive fly with wasp-like yellow and black banding on the abdomen, giving it an aposematic appearance. Adults are frequently observed visiting flowers for nectar and pollen in wet meadows, marshes, and fens, particularly in western and northern Europe. The species is associated with wetland habitats, where larvae develop aquatically or semi-aquatically in waterlogged soils, mud, decaying organic matter near water margins, and occasionally in dung. Larvae are elongated, flat-bodied, and breathe via a respiratory siphon at the tail end. Adults are strong fliers capable of covering considerable distances between habitat patches. Stratiomys chamaeleon is considered Near Threatened, reflecting the significant loss and degradation of wet grassland and fen habitats across Europe due to drainage for agriculture, peat extraction, and development. The species requires mosaics of open water, wet soil, and flowering plants to complete its life cycle. Conservation depends on wetland restoration and maintenance of traditional wet meadow management.
