ours blanc

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.

Rhodomonas abbreviata is a photosynthetic cryptophyte flagellate in the family Pyrenomonadaceae, characterized by its small, compressed cell with two unequal flagella and distinctive phycoerythrin pigments that give it a reddish coloration. It inhabits marine and brackish coastal waters where it contributes to nanophytoplankton communities. Cryptophytes like this species are important food sources for zooplankton and heterotrophic protists.
