Abstract

Diving times and hunting success of otters were compared in two freshwater lochs in Aberdeenshire and in the sea off Shetland. During each hunt, otters in the marine habitat caught significantly more prey items and each hunt was of longer duration than in the freshwater habitat. Most recorded prey caught in the sea were smaller and probably of lower nutritional quality than in the freshwater lochs.
