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.

Ustilago filiformis is a smut fungus in the family Ustilaginaceae, an obligate biotroph that infects reed grasses (Glyceria species) and transforms their floral parts into masses of dark teliospores. It manipulates host plant development to create galls in place of normal ovaries, which then disperse the fungal spores. Smut infections by Ustilago species can significantly reduce seed production of their grass hosts.
