阿拉斯加黑鲸可能是杰克·伦敦的传说。故事比比皆是的生存能力被冻结。雪橇犬吃冻黑鲸然后呕吐起来,鱼开始扑腾。厨师滴冻黑鲸成锅然后把他们跳出像爆米花。鱼类生物学家已经证明,黑色鱼无法生存完全冻结。但他们可以生存冻结的头部和皮肤。黑鲸生活在落后和池塘形成冰在冬天。他们有鳃和气体吸收的食道修改;他们可以呼吸空气和水。在冬天他们耐受低氧在水中。 If oxygen gets too low, they swirl the water near an ice hole to keep it open while breathing air. In a backwater, ice forms before the water recedes, leaving a space between the ice and bottom. The blackfish curls up in vegetation, secretes mucus over its body for insulation and breathes air until spring breakup. No wonder the Alaska Blackfish is the stuff of legends!
