ANIMAL NATION
Red Crab Crazy Ants

Located 223 miles south of Jakarta, Australia's Christmas Island is home to one of nature's greatest, most colourful and most spectacular natural mass migrations.

Each year this pristine island's shoreline is covered with an ankle-deep carpet of red crabs, as the females commence a spawning frenzy, each jettisoning their cache of 100,000 eggs into the sea.

Yet while this should be increasing their numbers, they are actually dropping due to an alien invader.

During their annual migration across the island many of the crabs are falling victim to the yellow crazy ant, which were accidentally introduced by immigrants more than 50 years ago.

These ants have disrupted the status quo and now not only are the red crabs future in jeopardy but entire ecology of the island is at risk.
