The back of the bulldog rat had a 2 cm layer of fat giving it a distinctive hump. 4. Course reddish-brown hair covering its body. 5. It was extremely sluggish, refusing to climb. It was reported the bulldog rat was “half-dazed in daylight” and was nocturnal. 6. This rat species preferred higher hills and thicker forests on the island. 7. They lived in small colonies under sago palm trees. 8. Black rats brought diseases to Christmas Island, killing off large numbers of bulldog rats. 9.

EXTINCTION DATE

1903

 

Christmas Island was named by William Mynors on Christmas Day 1643. The British’s first attempt to make a settlement on Christmas Island in 1857 failed. It wasn’t until 1886 that John Maclear discovered Flying Fish Cove, that a settlement began to take hold. Maclear took scientific notes about the plants and animals on Christmas Island. Unfortunately, it is believed that Maclear inadvertently brought invasive black rats to the island with him. These black rats would have devastating effects on Christmas Island’s two native rat species, the bulldog rat and the Maclear’s rat. Both native rat species were last seen in 1903. It is thought that a combination of factors, diseases, competition, and crossbreeding led to the extinction of the bulldog rat and the Maclear’s rat. The bulldog rat was a slow moving rat, native to Christmas Island. Records of the bulldog rat said that it was unafraid of humans and refused to climb trees. It was perfectly adapted to the tropical environment of Christmas Island, but it lacked the ability to adapt. Its sluggish nature did not help it escape the devastating effects of the black rat invasion. Although Jurassic Park is fiction, scientists are working on several de-extinction projects. In fact, in 2003 scientists did bring back the extinct Pyrenean ibex, a type of wild goat, for 7 minutes before it died, showing de-extinction is possible. The bulldog rat might be a candidate. Scientists would potentially use DNA from museum specimens that might be found. The Australian government has been working on initiatives to protect its native wildlife by restoring lost habitat and eliminating invasive species which have plagued the continent and surrounding island territories. Feral cats, crazy yellow ants, wolf snakes, and giant centipedes are just a few of the non-native species that have led to the extinction of so many animals. Australia has set up a Threatened Species Commissioner and federal environment minister to study these problems and look for solutions to save species currently at risk. Some people are trying to get Christmas Island to be labeled ‘World Heritage Site” to bring more public attention to the problems there. An island biodiversity monitoring program has been set up in Christmas Island as well. If the bulldog rat was brought back to life, could it ever be reintroduced to its native homeland in Christmas Island?
