Introduction: mammals and their reproduction aerial hunting and to life in water. Three major groups—monotremes, marsupials and placental mammals—exist today, distinguished on many points of anatomy and notably by their modes of reproduction. Some 4200–4500 living species are recognised (Morris, 1965; Harrison Matthews, 1969).作者: Limousine 時(shí)間: 2025-3-24 20:59
