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).

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.

Methanotorris igneus is a hyperthermophilic methanogenic archaeon in the order Methanococcales, thriving at temperatures near 88°C in deep-sea hydrothermal vent environments. It produces methane by reducing carbon dioxide with molecular hydrogen under strictly anaerobic conditions. Its thermostable enzymes have been of interest to biotechnology for their catalytic activity at high temperatures.
