Christmas Island’s Red Crab March
Christmas Island transforms into a sea of red every November. Millions of crimson crabs emerge from the forest, marching straight toward the ocean. Male crabs dig love nests in the sand, sometimes fighting over prime beachfront real estate. Females release their eggs precisely when high tide meets the last quarter moon. The larvae spin in offshore currents for a month before returning as tiny crabs no bigger than your fingernail.
