Gomphonema paludosum is a freshwater diatom in the family Gomphonemataceae, characterized by its asymmetrical, wedge-shaped frustule attached to substrates by a mucilaginous stalk. It inhabits shallow, standing waters, marshes, and boggy habitats where it grows on sediment surfaces, plant stems, and submerged debris. As a benthic diatom, it is a useful bioindicator of water chemistry and organic enrichment.

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.
