ABSTRACT
We tested the hypothesis that spatial arrangement and movements of bot-
tlenose dolphins (TursiopJ truncatm) are related to the spatial arrangement of
their prey. From 65 groups we: (1) classified feeding behavior of dolphins
according to spatial arrangement and movements of individuals; (2) assessed
spatial arrangement and location of prey from direct observations, numbers
of associated seabirds, and echosounder recordings; and (3) related feeding
