Habitat & Geographic Range

common bottlenose dolphin

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 12 distinct biome types. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Asia (Taiwan), Europe (6 countries), and South America (Colombia, Ecuador, Venezuela).

Common Yellow Rattle

Habitat

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

Range

Found across Europe (7 countries) and North America (United States). Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

common bottlenose dolphin

The most studied and recognized dolphin species, bottlenose dolphins inhabit warm and temperate oceans worldwide, from coastal shallows to the open sea. Highly intelligent with large brains relative to body size, they demonstrate self-recognition, complex communication, and social learning. They live in fluid fission-fusion societies and cooperate to herd fish. A keystone indicator species for marine ecosystem health.

Common Yellow Rattle

<em>Rhinanthus minor</em>, the common yellow rattle or little yellow rattle, is a hemiparasitic annual plant in the family Orobanchaceae. It is native to Europe and parts of western Asia, occurring in traditional hay meadows, calcareous grasslands, moorlands, and other nutrient-poor grassland habitats. The species attaches its roots to those of neighboring grasses and extracts water and nutrients from them, thereby weakening grass competition and promoting the establishment of a more diverse wildflower community. This ecological role has led to the deliberate introduction of <em>Rhinanthus minor</em> in grassland restoration projects across Britain and Europe. Plants typically reach 10–50 cm in height and bear inflated calices enclosing yellow tubular flowers, which rattle when the ripe seeds are shaken — the origin of its common name. Biological traits such as precise average lifespan measurements and body weight data remain poorly documented in consolidated scientific literature. Seeds germinate only in the presence of host grass roots. The species is assessed as Vulnerable, reflecting significant declines caused by the widespread loss of traditional hay meadow management and the conversion of grasslands to intensive agriculture across much of its European range.
