__________________________________. Unlike humans, whales are unable to protect themselves they are forced to come to the surface to breathe, where they are fully exposed to the sun's harsh rays. University of London researchers theorize that there may be some correlation between the severity of skin damage and the amount of time spent at the ocean's surface, which varies based on whale species.但鲸鱼却无法像人类那样保护自己,因为它们必须要浮出海面进行呼吸,那会让它们完全暴露在强烈的紫外线下.伦敦大学的研究人员推断,鲸鱼晒伤的程度可能与它们在海面上的暴露时间有关,而暴露时间又会因鲸鱼种类的不同而不同.
