Every year on the island of Cuba, female land crabs migrate from their forest home to the coastline in order to release their eggs into the Caribbean Sea. This video segment from Nature highlights the many obstacles the crabs have to overcome in order to complete this annual journey. They must protect themselves from dehydration in the Caribbean heat, as well as traffic while crossing busy roads and highways. The crabs have an instinctive ability to trace changing tidal patterns of the sea and manage to reach their final destination. They never stop; no matter what the adversity, an invisible drive compels them to the sea to spawn.
