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.

Habitat

Native to Europe, inhabiting ecosystems characteristic of the region.

Range

Distributed across Norway and Sweden.

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.

Chroomonas vectensis is a species of cryptophyte alga in the family Chroomonadaceae, with the specific epithet vectensis suggesting a type locality or particularly strong association with the Isle of Wight (Vectis in Latin), off the southern coast of England. If correctly attributed, this would place the type collection in the coastal or brackish waters of the Isle of Wight or surrounding seas, suggesting this species may be adapted to marine or brackish conditions, as opposed to the strictly freshwater Chroomonas species. Marine cryptophytes are significant contributors to coastal phytoplankton and are important prey items in marine food webs. Chroomonas vectensis would share the general characteristics of the genus — small biflagellate unicells with a cryptophyte plastid bearing phycobiliproteins and chlorophyll a and c — while potentially possessing adaptations to saline or brackish conditions such as osmotic regulation mechanisms. Marine cryptophytes have received increasing scientific interest for their potential as sources of EPA (eicosapentaenoic acid), a valuable polyunsaturated fatty acid. Conservation status has not been assessed by the IUCN.
