Habitat & Geographic Range

Buckelwal

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.

Coast Dart

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Distributed across Belgium, Denmark, Norway, and Sweden.

Buckelwal

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.

Coast Dart

Coast dart (Euxoa cursoria) is a medium-sized moth in the family Noctuidae, native to coastal sand dunes and sandy heathland habitats of northern and western Europe, including the United Kingdom, Denmark, the Netherlands, Germany, and Scandinavia. Adults are cryptically patterned in pale buff, grey, and brown tones that match the sandy substrates of their dune habitat, flying at night from late summer into autumn. Larvae feed on the roots of coastal dune grasses and other low-growing plants, overwintering as pupae in loose sand. The genus Euxoa includes numerous 'dart' moths distributed across the northern hemisphere, many of which are habitat specialists tied to open, sandy ground. Coast dart populations have declined significantly across their European range due to the stabilisation and vegetational succession of coastal sand dunes, reduction of bare sand patches through marram grass planting, and recreational disturbance. Despite these pressures, it is assessed as Least Concern by the IUCN. In the United Kingdom, it is classified as a priority species in the Biodiversity Action Plan and is the subject of dune management programmes aimed at maintaining open sand habitat.
