O objetivo do presente trabalho foi caracterizar o ritmo de atividade e tempo de digestão em Aegla longirostri Bond-Buckup & Buckup, 1994. Os animais foram coletados em Santa Maria, RS, Brasil. Em laboratório, os animais foram transferidos para aquários individuais (5L). Para testar a atividade locomotora e alimentar dos aeglídeos um grupo de animais permaneceu sob luminosidade constante durante 12 horas, enquanto outro grupo permanecia no escuro, essa condição sendo invertida a cada 12 horas. As observações foram realizadas a cada 6 horas. Para determinar o tempo de digestão os animais foram alimentados e a cada 30 minutos um indivíduo era sacrificado. Aegla longirostri mostrou menor atividade em períodos de luminosidade, o que aconteceu nos dois grupos de animais. Essa espécie leva aproximadamente 5 horas para concluir a digestão extracelular. Os resultados sugerem que A. longirostri possui hábitos noturnos e provavelmente se alimenta sempre que há recursos disponíveis. The aim of this work was to characterize the diel activity rhythm and time of digestion in Aegla longirostri Bond-Buckup & Buckup, 1994. The individuals were collected in Santa Maria, RS, Brazil. In laboratory, the animals were kept in individuals glass aquariums (5L). To test locomotor and feeding activity of the aeglids, a group remained under constant luminosity for 12 hours, while another group was mantained in the dark, this condition being reversed at each 12 hours. The observations were taken at every 6 hours. For the determination of digestion's time the animals were fed, and one individual was sacrificed at each 30 minutes. Aegla longirostri showed lower activity in periods of light time. This condition was recorded for both groups of animals. This species takes approximately 5 hours to conclude its extracellular digestion. The results suggest that A. longirostri has nocturnal habits and probably feeds whenever resources are available
