Bornean orangutan

The world's largest arboreal mammal, Bornean orangutans weigh up to 90 kg and spend most of their lives in the rainforest canopy of Borneo. Solitary and semi-nomadic, they build nightly sleeping nests in trees and forage for fruit, leaves, and invertebrates. Critically Endangered, with populations having declined by over 50% in the past 60 years due to deforestation from palm oil expansion and illegal hunting.

Buckelwal

Among the most acrobatic of the great whales, humpback whales are renowned for their complex, haunting songs sung by males during breeding season — some lasting hours and evolving over time. Reaching 16 meters and 30 tonnes, they undertake the longest migrations of any mammal. Found in all oceans, humpbacks feed on krill and small fish using cooperative bubble-net feeding. Populations have largely recovered from historic whaling.
