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.

Stenotrophomonas daejeonensis is a Gram-negative gammaproteobacterium in the family Xanthomonadaceae, first isolated from soil samples collected in Daejeon, South Korea. It is aerobic, rod-shaped, and motile by polar flagella. Like other Stenotrophomonas species, it exhibits broad enzymatic activity and has been isolated from diverse environments including soils, water, and clinical samples.
