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.

Cocoa moth

Habitat

Found across multiple habitat types including tropical and subtropical dry broadleaf forests, deserts and xeric shrublands, and Mediterranean forests and woodlands spanning the Afrotropic and Palearctic realms.

Range

Widely distributed across Africa (Cabo Verde), Asia (4 countries), Europe (30 countries), and North America (Canada, United States).

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.

Cocoa moth

The cocoa moth (Ephestia elutella) is a small moth in the family Pyralidae with a wingspan of 14–22 millimetres, cosmopolitan in distribution as a stored-product pest. The species is native to Europe but has spread globally through trade in stored commodities, particularly cocoa beans (from which its common name derives), dried fruits, tobacco, grain, nuts, and confectionery. Adults are greyish-brown with subtle patterning on the forewings; they are short-lived and do not feed as adults. Females lay eggs directly in or near food material; larvae are creamy-white with dark head capsules and spin silken webbing through infested commodities as they feed, causing significant post-harvest economic losses. Like other pyralid stored-product moths, E. elutella is a major pest of food processing and warehousing facilities worldwide, thriving in warm, dry storage conditions with high carbohydrate content. It has been recorded from at least 30 European countries and is present on all inhabited continents. Control relies on temperature treatment, pheromone-baited monitoring traps, and chemical insecticides, though resistance to some compounds has been reported. The species is classified as Least Concern by the IUCN, reflecting its global distribution and thriving populations in human-modified environments. Its economic importance has made it the subject of extensive research into stored-product pest biology, chemical ecology, and integrated pest management strategies.
