house mouse

Entre os mamíferos mais amplamente distribuídos e numerosos da Terra, os camundongos domésticos originaram-se no sul da Ásia e acompanharam a civilização humana por todos os continentes, exceto a Antártida. Pesando apenas 15–25 g, são onívoros altamente adaptáveis capazes de sobreviver com mínima quantidade de comida e água. Como o animal de laboratório mais comumente utilizado no mundo, o camundongo doméstico (Mus musculus) contribuiu para praticamente todos os ramos da pesquisa biomédica. Causam danos agrícolas significativos em nível global.

Polar bear

O maior carnivoro terrestre da Terra, o urso-polar pode ultrapassar 700 kg e e encontrado pelo gelo marinho artico, do Canada ate a Russia. Mamiferos marinhos altamente especializados que dependem do gelo marinho para cacas de focas e focas-barbadas. Excelentes nadadores capazes de percorrer grandes distancias em aguas abertas. Classificado como Vulneravel, com populacoes sob severa pressao devido a rapida perda de gelo marinho artico causada pelas mudancas climaticas.
