Meat Eaters [PDF ebook] 

Primeval jungles, mountain ranges, and the cover of deep forests are not the only domains of meat-eating creatures. Carnivores also can be found stalking prey from the air, in ocean depths, and marshy swamps. Raptors, sharks, and crocodiles are among the most predominant non-mammalian meat-eaters that rely on hunting or scavenging for survival. This volume examines the various species in this select grouping, investigating the physical characteristics and traits that help these unique animals be successful predators.
