Última Feeding behavior of the Neotropical freshwater stingray Potamotrygon motoro (Elasmobranchii: Potamotrygonidae) Neotropical Ichthyology Shibuya,Akemi; Zuanon,Jansen; Tanaka,Sho. The feeding mechanisms of elasmobranchs and their functioning have been receiving growing scientific attention, although less emphasis has yet to be directed towards batoid species. The present study investigated the use of orobranchial musculature during prey capture and processing behavior in Potamotrygon motoro. Ten orobranchial muscle groups were removed to determine their relative biomasses. The kinematics of the musculature was described based on videos of prey capture and manipulation under captive conditions recorded at 250 and 500 field/s. Analyses of the orobranchial musculature indicated that adductor muscles responsible for closing the mouth had high biomasses, which is consistent with their functions related to apprehend and manipulate the...
