Foraging patterns and prey selection in an increasing and expanding sea otter population
Laidre KL and Jameson RJ. 2006. Foraging patterns and prey selection in an increasing and expanding sea otter population. Journal of Mammalogy. 87(4):799-807
From the Abstract: "Focal observations of sea otter (Enhydra lutris kenyoni) foraging patterns and prey selection were collected in coastal Washington between 1993 and 1999. Records consisted of 13,847 individual dives from 841 feeding bouts ranging from 1 min to >4h. Average dive time was 55 s ... and average surface time was 45 s ... irrespective of dive success. At least 77% of all dives ... were successful prey captures ....The growth and expansion of a small and isolated sea otter population provides a unique opportunity to examine the relationship between dietary diversity and population status and explore similarities and differences between trophic paradigms established for sea otter populations at other localities."
