Nitzschia flexa is a pennate diatom (class Bacillariophyceae) with a characteristically curved or bent raphe system that gives the genus its distinctive appearance. It inhabits freshwater to brackish environments and contributes to benthic and planktonic algal communities. As a photosynthetic microalga, it plays a foundational role in aquatic food webs and primary production.

Bely Medved

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.
