Winter is on its way. Caribbean spiny lobsters make a long chain. It’s time for their yearly trip, or migration.

Many animals migrate. This means they move from one place to another. They look for food. They look for places to have babies. How do the lobsters know when to go? In fall, days grow shorter. The water gets colder. This tells the lobsters to be on their way.

Earth is a big magnet in the center. Some animals can feel it. They use it to find the right way. The lobsters use it, too.


Spiny lobsters link together during their long trip.
