Mammalian species are found throughout Saguaro National Park. Mammals are characterized by their fur and the ability to nurse their young with milk from modified sweat glands called mammary glands. Mammals are warm-blooded, or endothermic. Bats, the only flying mammal, are numerous throughout the park, as are bobcats and javelina.
Did You Know?
"Don't call ME pig!" Javelinas are able to eat spiny prickly pear pads with no obvious harm to their mouths, stomachs or intestinal tracts due to an enzyme in their saliva. Javelinas are not true pigs, they are peccaries, which are native to the Americas. True pigs are native to Europe and Asia. Wild pigs and boars are descended from true pigs brought over on boats to the new world.
