Biscogniauxia repanda is a pyrenomycete fungus producing flat, crust-like stromata with embedded perithecia on dead hardwood bark. It inhabits temperate and Mediterranean forests, growing on dead branches and stems of oak, chestnut, and other hardwood trees. This saprotrophic ascomycete decomposes dead hardwood and colonizes stressed or damaged trees.

blue whale

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.
