垂直大迁移说到大迁移,我们最熟悉的一定是春运了。然而,在海洋世界中,有一个远比春运壮观的迁移场面——海洋生物的垂直大迁移,而且这个迁移的频率更高——每天一次。总体来说,在全球的热带和温带海域,许多海洋动物晚上会游到上层比较温暖的海域寻找食物,而白天则躲到通光量较少的下层海域,这样既安全又可以减少能量消耗。不过,影响每种动物昼夜迁移的因素不尽相同,既包括内源性因素
Vertical migration said that the great migration, we are most familiar with is the Spring Festival. However, in the oceanic world, there is a spectacular migration scene far beyond the Spring Festival - a vertical migration of marine life that is more frequent - once per day. In general, in the tropical and temperate seas around the world, many sea animals swim in the warmer waters at night to look for food, while in the daytime they hide in lower-water areas where light is less likely to be safer and less energy intensive. However, the factors that affect the day and night migration of each animal vary, including both endogenous factors
