Grand Bahama, in the north of the Bahamas, sees higher rainfall and cooler winter temperatures. Much of the island is marshland and beaches are often quite swampy, due to the fact that the island began its life as a series of cays, and is still generally very low-lying.

Mutations may or may not produce discernible changes in the observable characteristics (phenotype) of an organism.
