What primary prey category forms the bulk of the Xingu River Ray's sustenance?
Answer
Mollusks (bivalves and gastropods)
The core of the Xingu River Ray's diet consists of mollusks, specifically both bivalves and gastropods, which are shelled creatures found near the river bottom. These hard-shelled items provide the majority of the required caloric intake for the ray. This reliance mandates the development of powerful crushing mechanisms, as the ray must access the soft tissues protected within these heavily calcified structures, establishing mollusks as the foundational component of its natural menu.
