baleine bleue

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.

Nemania serpens is a saprotrophic ascomycete fungus producing flat, black, crust-like stromata that creep along the surface of dead wood, particularly hardwood branches and logs. It is found across temperate forests in Europe and North America, where it plays a role in wood decomposition. This species is one of the more commonly encountered wood-inhabiting ascomycetes in deciduous woodland.
