'krill'不是某个国家的语言，而是一种动物的名称。Krill是指一种富含蛋白质、氨基酸和必需脂肪酸的大型浮游生物，生活在全球各大洋的低温水域中，是海洋生物链上的重要组成部分。它们的体型通常只有数厘米长，但数量极其庞大，是海洋中最丰富的生物资源之一。
以下是9个含有'krill'的例句，以英语为例：
1. Blue whales primarily feed on krill, consuming up to four tonnes per day.（蓝鲸主要以微小甲壳类为食，每天食用四吨左右。）
2. Many commercial fisheries target krill as a source of fishmeal and oil.（许多商业渔业以甲壳类为目标，以获得鱼粉和油。）
3. Antarctic krill are the most abundant species of krill, with a population estimated at over 500 million tonnes.（南极甲壳类是最丰富的甲壳类之一，总数估计超过5亿吨。）
4. Krill oil is a popular dietary supplement due to its high levels of omega-3 fatty acids.（由于富含高水平的欧米茄-3脂肪酸，甲壳油是一种流行的饮食补充剂。）
5. Adélie penguins rely heavily on krill as a food source, and changes in krill populations can have a significant impact on their survival.（阿德利企鹅严重依赖甲壳类作为食物来源，甲壳类数量的变化对其生存有着重大的影响。）
6. The krill fishery in the Southern Ocean is managed by the Commission for the Conservation of Antarctic Marine Living Resources.（南极洲的甲壳类渔业由南极海洋生物资源保护委员会管理。）
7. Krill are an important part of the diet of many marine animals, including whales, seals, and seabirds.（甲壳类是许多海洋动物的重要食物来源，包括鲸鱼、海豹和海鸟。）
8. The biomass of krill in the Southern Ocean varies greatly from year to year, depending on factors such as sea ice extent and ocean currents.（南极洲甲壳类的生物量因海冰范围和洋流等因素而年年不同。）
9. Scientists are studying the impact of climate change on krill populations, which could have far-reaching effects on the entire marine ecosystem.（科学家正在研究气候变化对甲壳类数量的影响，这可能对整个海洋生态系统产生深远影响。）
