“…Fish-eating species share a set of morphological, functional and behavioural features with trawling insectivorous bats: both groups have large feet and long fingers armed with well developed claws, suited for capturing prey from the water surface (Brosset and Delamare Deboutteville, 1966;Brosset, 1975;Jones and Rayner, 1988), and both share relatively large and pointed wings, with high aspect ratio, fitted to allow relatively slow flight in open environments (Norberg and Rayner, 1987). Consequently, several authors have suggested a close link between trawling insectivory and piscivory, considering the former as a possible preadaptation for the latter (e.g., Novick and Dale, 1971;Jones and Rayner, 1988;Kalko et al, 1998). A recently published research on the molecular taxonomy of genus Myotis revealed that the subgenus Leuconoe (Findley, 1972), which includes all trawling myotid species, is paraphyletic, and consequently constitutes an ecomorph that has evolved independently several times (Ruedi and Mayer, 2001).…”
