Distributed across Brazil and Sweden.

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.

Achlya bisexualis is an oomycete in the family Saprolegniaceae that decomposes organic matter in freshwater habitats and can act as a pathogen of fish and invertebrates under certain conditions. It exhibits a fascinating pheromone-based sexual reproduction system that has been extensively studied as a model for steroid hormone signaling in lower eukaryotes. Its mycelial colonies rapidly colonize dead insect and plant debris in slow-moving water.

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.
