Abstract
Terrestrial talpid moles are competent swimmers, apparently due to small size and air-trapping capacity of the pelage. C. cristata, a semi-aquatic talpid mole, was the best swimmer (approximate duration 1 h), with the long tail and hind legs contributing significantly to success; it was the only mole which attempted diving (2 min. submersion maximum). The first pictures of swimming North American talpids are included, emphasizing the lack of attention to many interesting problems associated with the aquatic behavior of terrestrial mammals.
