A. ramsayi, also known as the Australian sea lion, inhabits the southern and western coasts of Australia. They are known for their playful and social behavior, often seen lounging on sandy beaches or swimming gracefully in coastal waters. Males are larger with a distinctive mane, while females are smaller and sleeker.

A. ramsayi, commonly known as the plains-wanderer, is native to the grasslands of eastern Australia. Its primary geographical distribution includes the Riverina region of New South Wales and parts of northern Victoria.

The species inhabits native temperate grasslands that are characterized by sparse vegetation and open areas with low shrub cover. These regions experience a semi-arid climate with low to moderate rainfall, hot summers, and mild winters.

The plains-wanderer is adapted to live in environments with low vegetation density, which allows it to forage for seeds and insects on the ground. Its ecological niche involves being a ground-dwelling bird that relies on camouflage and minimal disturbance in its habitat to avoid predators.
