FAQ
- Why is the Sumatran orangutan critically endangered?
- It is restricted to a small, shrinking range in northern Sumatra, and ongoing deforestation for agriculture and logging has fragmented its habitat, leaving an estimated wild population of under 14,000. Source
- How is the Sumatran orangutan different from the Bornean orangutan?
- Sumatran orangutans tend to have thinner bodies, longer faces, and paler, longer hair than their Bornean relatives, and they spend more time in trees, likely to avoid predation by Sumatran tigers. Source
- Do Sumatran orangutans use tools?
- Yes, they are known to fashion sticks into tools for tasks such as extracting insects from tree bark or accessing seeds, and one wild individual was even observed using a chewed plant to treat a wound. Source
