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.

Red-legged Honeycreeper

A small, strikingly colored tanager-related honeycreeper, males display vivid royal blue plumage with bright red legs — the diagnostic feature giving the species its name — and a long, curved, yellow-tipped bill. Found in tropical and subtropical forest canopy from Mexico south to Bolivia and Brazil, including Trinidad. They probe flowers for nectar, and their long bill accesses flowers unavailable to shorter-billed birds. Important pollinators of tropical canopy tree flowers. Common and widespread across humid neotropical lowland forests.
