Abstract

The whale shark (Rhincodon typus) aggregates in the Mexican Caribbean from May to September to feed on mixed zooplankton patches and fish spawn. For the first time in this area, we present evidence of observations of whale sharks feeding on schools of small fish, two in 2017 (10 individuals per flight) and one in 2024 (19 individuals). This fact shows that there is another food source for the species at this site, which may be used as an alternative to meet their energy demands when zooplankton is scarce.

在墨西哥加勒比海北部，鲸鲨在捕食鱼群。

鲸鲨（Rhincodon typus）从5月到9月聚集在墨西哥加勒比海，以混合的浮游动物斑块和鱼卵为食。在这一领域，我们首次提供了观察到鲸鲨捕食鱼群的证据，2017年有两只（每次飞行10只），2024年有一只（19只）。这一事实表明，在这个地方有另一种食物来源，当浮游动物稀缺时，这可能是满足它们能量需求的另一种选择。
