  The most prolific wild mammals are a koala hedgehog in Madagascar and the comoros islands, it gave birth to a litter of 31 little hedgehog, including 30 surviving >

  无尾猬科起源于非洲大陆

  Koala hedgehog family originated in the continent of Africa

  无尾猬科起源于非洲大陆,很早就到达了马达加斯加岛,也是那里仅有的食虫目。由于没有其他食虫目竞争,马达加斯加岛上无尾猬科成员非常多样化,发展出了类似其他不同食虫目成员的代表,而非洲大陆则种类很少。马达加斯加岛的无尾猬科分成短尾而有刺的无尾猬亚科和长尾而无刺的稻田猬亚科。非洲的无尾猬科属于獭鼩亚科,而马达加斯加岛的穴居稻田猬过去曾被不同学者置于稻田猬亚科或獭鼩亚科。新近的研究表明其可单列为独立的穴居稻田猬亚科,是无尾猬科最原始的成员。无尾猬亚科种类较少,外形颇似刺猬,体型较大,其中无尾猬体长达40厘米,是食虫目中体型最大的成员之一。稻田猬亚科种类较多,比较多样化,是马达加斯加岛上最常见的哺乳动物之一。稻田猬亚科多数成员体型似鼩鼱,有些穴居略似鼹鼠,有些半水栖,有些树栖。獭鼩亚科为水栖成员,其中獭鼩体型颇似水獭,小獭鼩则和水鼹、水栖稻田猬、水鼩等水栖等水栖食虫类非常相似。

  Koala hedgehog originated in Africa, have long been arrived in Madagascar, is there only insectivorous. Since there is no other carnivorous mesh competition, Madagascar koala hedgehog family members are very diverse, to develop a similar other carnivorous mesh representatives of members of the different, while the continent type rarely. Madagascar's koala hedgehog into short tail and barbed koala hedgehog subfamily and long tail and paddy fields without a thorn hedgehog subfamily. Africa's koala hedgehog, belongs to the otter shrews subfamily, hedgehog Madagascar cave rice used by different scholars in paddy hedgehog subfamily or otter shrews subfamily. Recent studies have shown that it can be a single cave of paddy fields for independence hedgehog subfamily, hedgehog is one the most original member. Koala hedgehog subfamily species less, appearance is like a hedgehog, larger, hedgehog was up to 40 cm long, which one is the largest carnivorous eye of one of the members. Rice paddies hedgehog subfamily sort is more, more diversified, is one of the most common mammals in Madagascar. Paddy hedgehog subfamily most members shape like shrews, some cave slightly as the mole, some semi aquatic, some arboreal. Otter shrews subfamily for aquatic members, of which the shape as the otter otter shrews, little otter shrews and water Yan, aquatic paddy hedgehog, such as water shrew aquatic aquatic insectivora are very similar.
