Habitat & Geographic Range

Coelacanthe

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.

Coelacanthe

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.

grand dauphin, souffleur, dauphin à gros nez

The most studied and recognized dolphin species, bottlenose dolphins inhabit warm and temperate oceans worldwide, from coastal shallows to the open sea. Highly intelligent with large brains relative to body size, they demonstrate self-recognition, complex communication, and social learning. They live in fluid fission-fusion societies and cooperate to herd fish. A keystone indicator species for marine ecosystem health.
