Canadian beaver

北美最大的啮齿动物加拿大河狸体重可达32公斤，是栖息于加拿大和美国北部河流、湖泊和湿地的杰出生态系统工程师。通过伐木和建造可达数百米的水坝形成水塘，为数百种物种提供生境。其巢穴和运河改变了整个流域。曾因毛皮贸易被猎杀至濒临灭绝，但种群已大幅恢复。

giraffe

长颈鹿（Giraffa camelopardalis）是地球上最高的动物，身高可达5.5米，体重最重可达1,750千克。其细长的颈部——与所有哺乳动物一样包含七块颈椎——是为了在非洲稀树草原和林地取食金合欢树而进化的。长颈鹿是社会性动物，生活在无固定纽带的松散兽群中，通过次声波和肢体语言进行交流。由于栖息地丧失和偷猎，种群持续减少，被列为易危。
