鲸鱼会睡觉吗？根据研究人员的说法 圣安德鲁大学 伽利略杂志引用了这段话。 抹香鲸 是世界上最不依赖睡眠的哺乳动物，只使用 7%的时间用于休息 然而，即使是他们也需要偶尔打个盹--一位摄影师很幸运地记录了这一难得的时刻。
2008年，研究人员已经记录了一群该物种的鲸鱼在睡觉，这导致了关于这些动物睡眠的新发现。 然而最近，水下摄影师Franco Banfi发现这些鲸鱼在加勒比海的多米尼加共和国附近睡觉，并没有错过拍摄它们的机会。
这一刻的照片令人难以置信：
鲸鱼睡觉时一次只用一侧大脑。 就像海豚一样，它们是鲸类动物，通过肺部呼吸，必须浮出水面才行。 当它们睡觉时，一个大脑半球休息，另一个保持清醒，以控制呼吸和避免捕食者的攻击。 这种睡眠类型被称为单半球。
