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.

Spectacled Parrotlet

One of the world's smallest parrots, spectacled parrotlets reach just 12 cm in length and inhabit humid forests and woodland edges of Colombia, Panama, and Venezuela. Named for the striking blue eye-ring in males, these pocket-sized green parrots form flocks that move noisily through forest canopy foraging for seeds, berries, and fruit. Like many small neotropical parrots, they face pressure from habitat deforestation. They are popular in aviculture for their compact size and curious personalities.
