Crabs on the Move: The World’s Strangest Mass Migration

Send us Fan MailSubscribe and unleash your inner science goblin. We see you. We respect it.In this final Swarms Minisode of the season, Katy Reiss and Laura Fawks Lapole lose their minds (in the best way) over the most chaotic, moon-synced crab love party on Earth: the migration of Christmas Island red crabs.We’re talking: 🦀 50 to 100 million land crabs 🌧 Timed to what we're convinced is a witches curse.... 🚧 Roads shut down 🌊 Pina colada breaks (probably) 💥 And babies launched off seaside cliffs like nature’s carpet bombThis migration is so massive, locals build crab bridges and the entire island turns into one giant crustacean mosh pit.But here’s the kicker—these crabs know how far they are from the ocean… AND what phase the moon is in. With brains the size of a Tic Tac.🎧 Listen in for weird crab romance, the female egg drop of the century, and a surprising twist: these babies? They’re not just adorable—they’re lunch.
