blue whale

O maior animal que já viveu na Terra, as baleias-azuis podem atingir 33 metros e 200 toneladas — seus corações sozinhos pesam tanto quanto um carro pequeno. Encontradas em todos os oceanos, migram entre áreas de alimentação polares e áreas de reprodução tropicais. Filtradores que consomem até 4 toneladas de krill diariamente. Em perigo, com populações globais estimadas em 10.000–25.000 após a quase extinção causada pela caça baleeira no século XX.

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.
