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.

Fork-tailed Woodnymph

A brilliantly colored South American hummingbird named for its deeply forked tail, fork-tailed woodnymphs display glittering violet-blue gorget and green upper parts in males, with deep blue forked outer tail feathers. They are widespread in tropical forests east of the Andes from Venezuela and Colombia to Bolivia and Brazil. Highly aggressive territory defenders, they chase other hummingbirds from nectar sources. They are important pollinators of diverse Amazonian and Atlantic Forest flowering plants.
