Active touch performance in the Antillean manatee: evidence for a functional differentiation of facial tactile hairs.
Zoology: Analysis of Complex Systems 102(1): 61-69. 5 figs.
–Abstr.: Bachteler & Dehnhardt, 1998. In texture discrimination experiments, a juvenile T. m. manatus at Nuremberg was able to distinguish as little as a 14% difference in width of grooves 2-10 mm wide. The lips, perioral bristles, and bristle-like hairs of the oral disc were all used in exploring the stimuli, but only the last were used for touching after acquisition of the stimuli. The tactile resolving power of the bristle-like hairs is lower than that of pinnipeds, but compares well with that of the trunk of Asian elephants.
