LOCOMOTION IN AQUATIC, TERRESTRIAL, AND ARBOREAL HABITAT OF THICK-TAILED OPOSSUM, LUTREOLINA CRASSICAUDATA (DESMAREST, 1804)

摘要: The reasons Lutreolina crassicaudata is always captured in close proximity to water are not clear. We investigated locomotory behavior and performance swimming, running, climbing, jumping of L. crassicaudata. One adult male was videotaped the laboratory while walking on ground a horizontal tube 1.2 m from ground, climbing tree trunk angled 458, gaps between supports. locomotor cycles these different activities were described by speed, stride length, stroke or frequency, time power recovery phases stance swing phases, displacement points animal. employed quadruped paddling gait swimming. Swimming speed similar that terrestrial didelphids, but frequency buoyancy ability more those opossum. Different gaits used for locomotion each habitat type we conclude cannot be considered specialized species aquatic locomotion.
