THE MAGNIFICENT MARIANAS FRUIT BAT (Pteropus mariannus) has been hunted almost to extinction on many of the Marianas Islands. Today, only a small population of between 500 and 600 of these bats survives on Guam, and a second species (P. tokudae) endemic to the island, has recently become extinct. This colony, the last on the island of Guam, is now protected under the U.S. Endangered Species Act.
