Habitat & Geographic Range

blue whale

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.

cockscomb sainfoin

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Belgium, France, Netherlands, and United Kingdom.

blue whale

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

cockscomb sainfoin

Cockscomb sainfoin (Onobrychis caput-galli) is a slender, annual or biennial legume in the family Fabaceae, native to dry, rocky grasslands, field margins, and garrigue scrub of western Europe, primarily in Belgium, France, the Netherlands, and the United Kingdom, extending into the Mediterranean basin. Growing to 20–50 centimetres, the plant has pinnately compound leaves and produces loose racemes of small pink to mauve pea flowers in late spring and early summer. The distinctive winged, helmet-shaped pods — resembling a cock's head or comb — give the species both its common and scientific names (caput-galli meaning cock's head in Latin). Unlike the closely related common sainfoin (Onobrychis viciifolia), this species does not spread by creeping rhizomes and is less commonly used in agriculture, though it grows in similar calcareous, well-drained soil conditions. The plant is associated with dry chalk and limestone grasslands, a habitat under significant pressure from agricultural intensification, scrub encroachment, and development across much of its European range. Pollination is primarily by bees attracted to the nectar-rich flowers. Onobrychis caput-galli is Not Evaluated on the IUCN Red List at global scale, though it may be considered locally rare or declining in parts of its northwestern European range where appropriate grassland habitats have diminished substantially over the past century.
