Its body & abilities

• Weight: Large males reach around 85-90 kg; females are much smaller.

• Strength: A single hop can cover up to about 8-9 m in length.
• Senses: Sharp eyesight and hearing, with large ears that swivel to catch sound.
• Growing up: A tiny newborn crawls into the mother's pouch and stays there for months to keep growing.

Where it lives

• Habitat: Arid and semi-arid grasslands, scrub, and deserts.
• Where in the world: Across most of mainland Australia's dry interior.
• Territory: Ranges widely to find food and water rather than defending a fixed territory.

• Conservation: Least Concern (IUCN), with large, stable populations.

Life & legacy
