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.

Eunotia bactriana is a freshwater diatom in the family Eunotiaceae, featuring a distinctly curved frustule with fine transapical striae characteristic of the genus. It grows attached to mosses, sediment, and submerged plant surfaces in oligotrophic, acidic freshwater habitats. Like other Eunotia species, it serves as a bioindicator of pH and nutrient status in aquatic systems.
