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.

Bengkawat (Kalimantan)

The world's largest bat species, large flying foxes have wingspans reaching 1.5 meters and inhabit tropical forests from Southeast Asia to the Philippines and Indonesia. Despite the alarming name, they feed exclusively on fruit and nectar, making them vital pollinators and seed dispersers for tropical forest trees. Roost in massive colonies of thousands. Listed as Vulnerable due to hunting for bushmeat and habitat destruction.
