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.

Coconut rhinoceros beetle

Habitat

Typically found in virtually all terrestrial and freshwater habitats.

Range

Widely distributed across Africa (Mauritius), Asia (8 countries), North America (United States), and Oceania and the Pacific (7 countries).

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.

Coconut rhinoceros beetle

The Coconut Rhinoceros Beetle (Oryctes rhinoceros) is a large scarab beetle in the family Scarabaeidae, notorious as one of the most destructive insect pests of coconut and oil palms across tropical Asia and the Pacific. Adult beetles measure 40–60 millimetres in length and are characterized by a prominent horn projecting from the head of males, used in intraspecific combat for mating access. Adults bore into the growing apex of palm crowns to feed on sap, creating characteristic V-shaped cuts in fronds and weakening trees so severely that they may die. Larvae develop in decaying organic matter, particularly rotting logs, compost heaps, and dead palm trunks. Native to South and Southeast Asia, the beetle has spread through accidental introduction to the Pacific Islands, including Palau, Guam, Hawaii, and the Solomon Islands, where it threatens both agricultural productivity and native palm ecosystems. In Mauritius, introduced populations have caused significant damage to ornamental and cultivated palms. Biological control programs employ the Oryctes nudivirus and entomopathogenic fungi such as Metarhizium anisopliae to suppress populations. Integrated pest management strategies combining pheromone trapping, sanitation of breeding sites, and biological agents have met with variable success. The species is not formally evaluated for conservation status given its pest rather than threatened nature.
