Carnivora ( ) is an order of placental mammals specialised primarily in eating flesh, whose members are formally referred to as carnivorans. The order Carnivora is the sixth largest order of mammals, comprising at least 279 species. Carnivorans are found on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. Carnivorans exhibit a wide array of body plans, varying greatly in size and shape.
Carnivora is an order of meat-eating mammals that includes at least 279 species, making it the sixth largest group of mammals, and its members are found across nearly every environment on Earth, from polar regions to deserts to oceans. These carnivorans are important to understand because they display remarkable diversity in size, shape, and habitat, revealing how one specialized diet strategy has evolved into many different forms of life across the planet.

维基物种中的分类信息:食肉目 食肉目(学名:Carnivora)在动物分类学上是哺乳纲中的一个目。食肉目包括260多种胎生的动物。除杂食的熊科(比如主要吃竹叶的大熊猫),绝大部分均在不同程度上以其他鸟兽、两栖类、爬行类和鱼类为食。食肉目动物分布几乎全世界各地。具有發達的門齒與犬齒。 目录 1 特征 2 分类 2.1 种系发生学 3 注释 4 参考文献 特征 食肉目动物犬齿大而尖锐,上颌最后一个前臼齿和下颌第一个臼齿特别发达,称为“食肉齿”、“裂齿”或“裂肉齒”;食肉目动物爪子锐利,有些种类能收缩;大脑发达,具有脑回。 食肉目动物是哺乳动物各目中体型差异最大的一个目,体型最小的伶鼬(Mustela nivalis)只有25克,11厘米,北极熊(Ursus maritimus)则可以重达1000公斤,体型更大的南象海豹雄性可以达到2,270公斤以上,体长可达4.2米。 分类 食肉目 Carnivora 犬型亚目 Caniformia †犬熊科 Amphicyonidae 犬科 Canidae 熊型下目 Arctoidea 鼬总科 Musteloidea 小熊猫科 Ailuridae 臭鼬科 Mephitidae 浣熊科 Procyonidae 鼬科 Mustelidae 鳍足形类 Pinnipedimorpha 鳍足类 Pinenipedia †海熊兽科 Enaliarctidae 海象科 Odobenidae 海狮科 Otariidae 海豹科 Phocidae 熊总科 Ursoidea †半狗科 Hemicyonidae 熊科 Ursidae 猫型亚目 Feliformia †猎猫科 Nimravidae †中鬣狗科 Precrocutidae 双斑狸科 Nadiniidae †Aeluroidea超科 †Stenoplesictidae科 猫总科 Feloidea †巴博剑齿虎科 Barbourofelidae 林狸科 Prionodontidae 猫科 Felidae 灵猫下目 Viverroidea 灵猫科 Viverridae 獴总科 Herpestoidea 食蚁狸科 Eupleridae 鬣狗科 Hyaenidae 獴科 Herpestidae 种系发生学 食肉目各科演化关系如下: 食肉目 Carnivora 貓型亞目 Feliformia †獵貓科 Nimravidae †Stenoplesictidae †中鬣狗科 Percrocutidae 双斑狸科 Nandiniidae 猫总科 Feloidea 林狸科 Prionodontidae †巴博劍齒虎科 Barbourofelidae 猫科 Felidae 灵猫下目 Viverroidea 灵猫科 Viverridae 獴总科 Herpestoidea 鬣狗科 Hyaenidae 獴科 He
Carnivora ( ) is an order of placental mammals specialised primarily in eating flesh, whose members are formally referred to as carnivorans. The order Carnivora is the sixth largest order of mammals, comprising at least 279 species. Carnivorans are found on every major landmass and in a variety of habitats, ranging from the cold polar regions of Earth to the hyper-arid region of the Sahara Desert and the open seas. Carnivorans exhibit a wide array of body plans, varying greatly in size and shape.
Carnivora are divided into two suborders, the Feliformia, containing the true felids and several animals; and the Caniformia, containing the true canids and many animals. The feliforms include the Felidae, Viverridae, hyena, and mongoose families, the majority of which live only in the Old World; cats are the only exception, occurring in the Old World and the New World, entering the Americas via the Bering land bridge. The caniforms include the Caninae, Procyonidae, bears, mustelids, skunks, and pinnipeds that occur worldwide with immense diversity in their morphology, diet, and behaviour.
