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.

Common Pinmould

Habitat

Native to Europe and South America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Belgium, Brazil, Denmark, and Norway.

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.

Common Pinmould

<em>Mucor mucedo</em>, the common pin mould, is a zygomycete fungus in the family Mucoraceae, belonging to one of the earliest-diverging lineages of terrestrial fungi. It is characterised by long, unbranched sporangiophores topped with spherical, pin-like sporangia that release large numbers of asexual spores, giving infested substrates a grey or white mouldy appearance. The species is a saprotrophic decomposer, typically colonising dung, soil, decaying organic matter, and stored food products, where it plays a role in nutrient cycling and organic matter breakdown. <em>Mucor mucedo</em> is distributed across Europe, with records from Belgium, Denmark, and Norway, and in South America including Brazil, and is likely cosmopolitan given the ease with which its spores disperse through the air. It is assessed as Not Evaluated on the IUCN Red List, as fungal conservation assessments remain incomplete globally. Sexual reproduction involves the fusion of compatible mating types to produce resistant zygospores. Biological traits such as colony growth rates under standardised conditions, typical biomass production, and detailed ecological roles beyond general decomposition remain poorly documented in the scientific literature. The species is non-pathogenic to healthy humans but may cause opportunistic infections in immunocompromised individuals.
