Taxa de substituição horizontal de dentes no peixe-boi

P Domning, DarylM. Magor, Diana

Summary Teeth shed from the horizontally-advancing tooth rows of captive Amazonian manatees (Trichechus inunguis) indicate a rate of tooth row movement of about 1 mm/month. The movement appears to be initiated by weaning and continues throughout life, with variations in rate correlated with overall growth rate but independent of rate of tooth wear.
