Polar bear

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.

Rhabdogloea gorskii is a colonial cyanobacterium forming elongated, rod-shaped cells arranged within a common mucilaginous matrix in freshwater plankton communities. It is found in lakes and reservoirs across temperate regions and contributes to phytoplankton diversity. Like other cyanobacteria, it can form blooms under eutrophic conditions when nutrient levels and temperatures are elevated.
