Habitat & Geographic Range

Coelacanth

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 8 distinct biome types spanning the Australasia and Afrotropic and Indomalayan realms. Populations are also found in montane and highland environments at higher elevations.

Range

Distributed across Comoros, Indonesia, Mozambique, and South Africa. Currently classified as Critically Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.

Epaulard

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, Venezuela).

Coelacanth

A living fossil thought extinct for 65 million years until rediscovered off South Africa in 1938, coelacanths can reach 2 meters and 90 kg. They belong to an ancient lobe-finned lineage more closely related to tetrapods than to ray-finned fish, making them scientifically invaluable for understanding vertebrate evolution. Found in deep rocky reef habitats of the Indian Ocean, they are nocturnal and undergo internal fertilization, giving birth to fully formed live young. Critically Endangered.

Epaulard

The largest member of the dolphin family, orcas reach up to 9 meters and 6 tonnes and are found in every ocean from Arctic to Antarctic. Apex predators living in matrilineal pods with distinct dialects, hunting strategies, and cultural traditions that differ between populations. Some populations specialize in fish, others in marine mammals. No natural predators; orcas sit at the top of every marine food chain they inhabit.
