Prairie vole
A prairie vole pauses as it makes his way through the grass. The voles, common to the U.S., are known to mate for life. But University of Florida zoologists have found some male voles have multiple sexual partners because certain regions of their brain lack structures important to monogamy. The researchers speculate that these voles, which tend to face attack from faithful males, have poor memories of attacks, so they return again and again to try to mate with the females -- sometimes successfully.
