Blauwal

The largest animal ever known to have lived on Earth, blue whales can reach 33 meters and 200 tonnes — their hearts alone weigh as much as a small car. Found in all oceans, they migrate between polar feeding grounds and tropical breeding areas. Filter feeders consuming up to 4 tonnes of krill daily. Endangered, with global populations estimated at 10,000–25,000 after near-extinction from 20th-century whaling.

Weiden-Dickfuß

Cortinarius urbicus is a robust, fibrous-capped mushroom in the Cortinarius genus with a silky brown cap and rust-spored gills at maturity. It inhabits coniferous and mixed forests, forming ectomycorrhizal associations with spruce, pine, and occasionally deciduous trees. This fungus obtains nutrients by trading sugars with its tree partners in forest soil environments.
