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.

Steccherinum lacerum is a tooth fungus in the family Polyporaceae, assessed as Near Threatened (NT). It grows on dead wood of broadleaf trees, producing resupinate or semi-resupinate fruiting bodies with small, spine-like teeth. Its near-threatened status reflects sensitivity to the loss of large, fallen deadwood in managed forests.
