Abstract
In this paper, data on growth of the encephalon, sense organs and other feeding-related structures in Encrasicholina purpurea are analyzed. Allometric indexes of length of the different parts of the encephalon in relation to standard length (SL) were obtained. Growth of ocular lenses is isometric in organisms less than 25 mm SL, whereas positive allometric values were obtained for individuals 25+ mm SL. Growth of pectoral fins showed a similar pattern. During the life history of this species, visual perception is more important than olfactory sense for prey detection. Only larvae display tilter-feeding, while adults feed through deglutition and biting.
