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).

Bitrichia chodatii is a loricate chrysophyte (golden alga) in the order Chromulinales, forming a distinctive lorica with two or more projecting spines that anchor it to submerged surfaces or other algae. It inhabits oligotrophic, clear freshwater lakes, where it contributes to phytoplankton communities as a photosynthetic flagellate. Named in honor of botanist Robert Chodat, it is characteristic of cool, low-nutrient alpine and boreal lakes.

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.
