Research by Gusztak et al. (this issue, pp. 438–463) shows that this species consistently elevates its core body temperature by ~1°C immediately before entering the water and that it employs behavioral thermoregulation to maintain it at or above resting levels during aquatic foraging bouts. This behavior likely heightens the impressive sensory abilities, reaction times, and hence foraging efficiency of this diminutive predator (photo taken at Willard Lake, Ontario, by Glenn Tattersall). Top right, a shrew at the water’s edge (photo taken at Willard Lake, Ontario, by Joe Pontecorvo). Bottom right, up to 50%–80% of American shrew food intake comes from minnows, tadpoles, insect larvae, nymphs, crayfish, and other aquatic invertebrates (photo taken in Winnipeg, Manitoba, by Robert A. MacArthur).
