The reason for travelling to Christmas Island at Christmas is to see the red crab migration, it hadn’t occurred to me to study this in any great detail before leaving and so I wasn’t really sure what to expect.

The first thing that became apparent to me when we arrived was there is a trilogy of crab migrations, apparently the blokes all go down to the ocean early to get ahead of the woman folk, They do the normal things and build a home for the new bride, and hang around waiting for the ladies to turn up.
