Prenatal development in greater mouse-eared bat, Myotis myotis (Borkhausen, 1797) (Chiroptera, Vespertilionidae).

Order Chiroptera is the second largest mammal group after rodents. An understanding of the development of the bats, which is a very special mammal group in terms of their lifestyles, morphology and their ability to fly, is very important because most of the adult anatomical differences characterizing species occur during organogenesis. In this study, developmental stages were determined for Myotis myotis species based on external morphological characteristics from embryos obtained from wild-caught pregnant females. The developmental stages of M. myotis were comparable with those of other bat species.
