Chaetoceros diversus is a marine planktonic diatom belonging to one of the most species-rich diatom genera. It forms chain-like colonies of siliceous cells bearing long, needle-like setae (chaetae) that reduce sinking rates in the water column. This diatom inhabits coastal and open ocean environments worldwide and plays a significant role in marine primary production and global carbon cycling.

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.
