摘要在马拉维湖观察到两种形态学上专门用于刮藻类的慈鲷，它们也广泛地以浮游动物、浮游植物、碎屑、鱼苗和鱼卵为食。这些实地观察证实了实验室研究，慈鲷是兼性的，在他们的喂养剧目。这种能力有助于慈鲷科的成功。我们假设，形态专业化成为至关重要的食物资源时，低和有效的种植是必需的。
SummaryTwo cichlid species morphological specialized for scraping algae were observed in Lake Malawi also to feed extensively upon zooplankton, phytoplankton, detritus, fish fry and fish eggs. These field observations confirm laboratory studies that cichlids are facultative in their feeding repertoire. Such an ability contributes to the success of the family Cichlidae. We hypothesize that the morphological specializations become critically important when food resources are low and effective cropping is required.
