East Africa is famous for the wildebeest migration, but other mass migrations can also be awesome. At the Coast, I have been fortunate to witness the migration of tiny isopods, less than one centimeter in length. These creatures are crustaceans, related to the crabs and prawns, but living on land.
At times these isopods congregate in millions and migrate over the landscape. Their many millions of feet make a rustling noise on the dry leaves.
