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.

Ochrolechia pallescens is a crustose lichen in the family Ochrolechiaceae, assessed as Endangered (EN). It grows on bark of old trees and is considered an indicator of ancient woodland with long ecological continuity. Its endangered status reflects severe decline due to loss of old-growth and veteran trees across its range.
