Actually, Christmas Island crabs, which migrate around Christmas, and were the subject of an NPR story yesterday:
Palm fronds, turquoise lagoons and a clattering army of crustaceans making their way from the island's forest to the beaches. Christmas Island red crabs - 50 million of them. Jahna Luke works for Christmas Island's tourism association and lives there. She says everyone has a hand in the crabs' journey.
JAHNA LUKE: We have all these measures in place to keep the crabs safe while they make their migration down to the ocean. Even cars on the island - we all have rakes in our cars so that on our way to work or wherever it is we need to go, we - we're out raking the crabs off the road to clear our way.
It's a real thing, and not just because NPR talked about it:
So if you feel crabby this week, imagine being on Christmas Island, which should not be confused with Kiritimati. We'll return to Kiritimati in about a week, as they will be the first place on earth to enter the 2020s. Meanwhile, enjoy the crabs.
