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.

Kurthia huakuii is a Gram-positive rod-shaped bacterium in the family Planococcaceae, first characterized from Chinese environmental samples. Like other members of the genus, it is aerobic, non-spore-forming, and can be motile by peritrichous flagella at certain stages of growth. Members of the genus Kurthia are saprophytic bacteria found in soil, decaying organic matter, and animal products.
