The take-home message: Indo-Pacific crocs probably don't go rafting across ocean basins very often, but – given their skill at riding currents and their long-term durability in saltwater – if they do find themselves out on the high seas, they may well endure long enough to colonise some far-off beach. After chilling on the shore a few months, the croc hopped a northbound nearshore current and rode it to the tip of the peninsula in eight days.

A crocodile killed at Ailinglaplap Atoll in the Marshall Islands in 2004 was some 1,200 miles from the nearest known population. Although these crocodiles spend most of their lives in saltwater, they cannot be considered marine reptiles the same way sea turtles are, because the crocs rely on land for food and water. Research from the Cape York Peninsula in northeastern Australia, a global stronghold for the Indo-Pacific crocodile, has offered intriguing clues on how this reptile might have come to occupy such a gigantic and briny jurisdiction.
