Dentro da classificação dos animais vertebrados, os mamíferos são os mais importantes. As fêmeas desta espécie possuem glândulas mamárias que secretam leite, alimento indispensável aos mamíferos da mais tenra idade.

Informações e características dos mamíferos

A maioria dos mamíferos possui pêlos, alguns possuem o corpo parcialmente coberto,enquanto que outros possuem pêlos por todo o corpo.

Objetivamente podemos dizer que seu coração possui as seguintes características: quatro câmaras, artéria aorta curvada para a esquerda e diafragma que separa as cavidades do peito do abdômen.

Sangue dos mamíferos

O sangue dos mamíferos mantém-se sempre aquecido, ou seja, esta espécie possui uma temperatura corporal que independente da temperatura do meio externo.

Grupos que fazem parte

O grupo dos animais mamíferos é bastante vasto, fazem parte deste grupo os Marsupiais (exemplos: gambá, cangurú e coala), espécies na qual ocorre o desenvolvimento da cria principalmente na parte externa do corpo da fêmea, dentro de uma bolsa chamada marsúpio.

Também se incluem neste grupo animais carnívoros terrestres como, por exemplo, gato, cachorro e urso, assim como animais aquáticos como foca, leão marinho e morsa.

Há ainda outros mamíferos aquáticos como as baleias, os golfinhos, que fazem parte da ordem cetácea (animais marinhos pertencentes à classe dos mamíferos), peixes-boi, dugongos, que são os menores membros da ordem Sirenia (ordem de mamíferos marinhos).

Os elefantes (da ordem proboscídea) são mamíferos placentários, que se caracterizam pela presença de um nariz desenvolvido em forma de tromba; os morcegos, que são os únicos animais mamíferos (ordem Chiroptera) capazes de voar, representam um quarto de toda a fauna de mamíferos do mundo.

Há ainda outros mamíferos pertencentes a outras diferentes ordens como a preguiça, o tatu e o tamanduá (ordem Edentata); o castor, a marmota, o porco espinho e o esquilo (ordem Rodentia).

Há dois grupos de animais mamíferos de casco, sendo eles a maior parte dos membros da ordem dos Perissodactyla (grupo de mamíferos terrestres ungulados com um número ímpar de dedos nas patas, que inclui os cavalos, os tapires e os rinocerontes) e a ordem Artiodactyla (os artiodátilos formam uma ordem de animais mamíferos ungulados com um número par de dedos nas patas, é um grupo muito variado, com cerca de 220 espécies descritas, que incluem muitos animais com grande importância econômica para o homem, como o boi, a cabra, o camelo, o hipopótamo, o porco, etc.).

Os Humanos também pertencem ao grupo dos animais mamíferos (ordem dos Primatas) e os macacos também seguem esta mesma ordem.

Classificação científica dos mamíferos:

Domínio: Eukaryota
Reino: Animalia
Subreino: Metazoa
Filo: Chordata
Subfilo: Vertebrata
Infrafilo: Gnathostomata
Superclasse: Tetrapoda
Classe: Mammalia

Exemplos de animais mamíferos: homem, baleia, porco, boi, cachorro, gato, girafa, cavalo, leão, rato, canguru, elefante, macaco, urso, anta, onça, raposa, leopardo, lontra, peixe-boi, cervo, javali, lobo guará, jaguatirica, puma e doninha.

Curiosidade:

- A baleia azul (Balaenoptera musculus) é o maior mamífero do mundo. Seu comprimento é de aproximadamente 30 metros e seu peso pode chegar a 140 tonedas.
