Which three categories of vertebrates span the documented prey items for the various Yarara species across the group?
Answer
Amphibians, reptiles, and mammals
While the diet shifts based on age and local availability, the overall documented spectrum of prey consumed by the group of snakes broadly known as Yarara encompasses several major classes of vertebrates. Across the entire group, established prey records consistently show consumption across amphibians, reptiles, and mammals. Although birds are also consumed, they fall under the broader category of vertebrates, and the foundational spectrum mentioned highlights these three primary groups: amphibians (like frogs), reptiles (like lizards), and mammals (like rodents), representing the staple food sources utilized throughout their various life stages.
