Bramble Cay Melomys

The Bramble Cay Melomys was a small rodent that lived and foraged in the vegetation of Bramble Cay, a low lying sandy island formed on the surface of the Great Barrier Reef. It was Australia's most isolated mammal.

The Bramble Cay Melomys was the first species to be declared extinct because of climate change. Sea level rise and storm surges washed away its habitat, food and the last of the population. In 2014 scientists went searching in the hopes of starting a breeding program but were unable to find a pair. Other sea birds and turtles that live on the Cay are also threatened by storm surges and sea level rise.

Other animals at risk

Black-footed Albatross
The Black-Footed Albatross lives up to 60 years and may travel thousands of miles in a lifetime, using a specialized gliding technique that saves muscle and energy. It is able to smell food across vast expanses of ocean. Mates court for two years and pair for life.

Beluga
Belugas make such a variety of sounds—clicks, twitters, whistles, and mimics of other sounds—they have been nicknamed "sea canaries." As much as 40% of their body mass is blubber, which stores energy and keeps them warm in temperatures as low as 0 °C. The smallest whale on the planet, a baby Beluga gains up to 200 pounds a day.

Rusty Patched Bumble Bee
Bees have existed on the planet for at least 40 million years. There are 250 species of bumblebees and seven species of honeybees. Fatter and furrier than honeybees, bumble bees make only a small amount of honey for their own food.
