Synopsis

On an island 360 kilometres (223 miles) south of Jakarta, one of

the most extraordinary biological events on earth takes place -

the amazing red crab migration and spawning.



Each year millions of these creatures head to the Christmas

Island coastline for a spectacular mass spawning. But while this

should be increasing their numbers, the reverse is happening.



During the annual migration across the island, the red crab faces

enemies in many different forms, including minute yellow crazy

ants. These ants release formic acid as they crawl over and

around the crabs which, with no defence against the ferocity of

the onslaught, become stressed and die within hours.



Scientists examining the problem must find a way to prevent

these attacks and in doing so save the ecology of the Christmas

Island rainforest.
