What structural characteristic defines the bulk of the *P. leopoldi* diet?
Answer
Prey protected by hard exoskeletons or shells
The defining feature of the primary food sources consumed by the Xingu River Ray is the presence of a hard exterior, specifically the shells characteristic of bivalves and gastropods. Since the ray relies heavily on these mollusk species for its caloric needs, its feeding apparatus must overcome this natural defense mechanism. This necessity for physical breakage, rather than simple ingestion of soft tissue, is what drives the evolutionary adaptation of its powerful jaws and crushing teeth.
