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.

Navicula caterva is a freshwater pennate diatom in the family Naviculaceae, forming aggregations in benthic communities on sediment and submerged surfaces. Its symmetrically lanceolate frustule and central raphe are characteristic of the large and cosmopolitan genus Navicula. As a bioindicator, it is used in assessments of freshwater quality and trophic status.
