  • The Bramble Cay melomys, which looked like a small brown rat, lived on Bramble Cay, a hump of coral just 340 m long and 150 m wide that juts out three metres or less.
  • The rodent was known to have lived only on Bramble Cay, a minuscule atoll in the northeast Torres Strait, between the Cape York Peninsula in the Australian State of Queensland and the southern shores of Papua New Guinea.
  • The long-tailed, whiskered creature, called the Bramble Cay melomys, was considered the only mammal endemic to the Great Barrier Reef.
