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.

Curtobacterium ammoniigenes is a Gram-positive actinobacterium in the family Microbacteriaceae, isolated from soil and plant-associated environments. It is aerobic, rod-shaped, and motile by a single flagellum, and is capable of producing ammonia from organic nitrogen compounds. The genus Curtobacterium is commonly found in agricultural soils and the phyllosphere of various crop plants.
