生活压力增大让很多人受到焦虑的困扰。除了人类,其他一些脊椎动物,如斑马鱼、啮齿动物也会产生焦虑情绪。最新研究发现,遭受焦虑侵袭的不限于脊椎动物,小龙虾也会焦虑。研究人员把小龙虾放入一个十字架状的水族箱中。水族箱的一条通道光线明亮,另外一条保持黑暗。小龙虾喜欢在黑暗环境中生活,同时它们也爱探索整个水族箱,包括明亮的地方。当然他们在黑暗中停留的时间更长。 Increased pressure on life so many people are worried about anxiety. In addition to humans, other vertebrates, such as zebrafish and rodents, also develop anxiety. The latest study found that anxiety attacks are not limited to vertebrates, crayfish also anxiety. Researchers put crayfish into a cross-shaped aquarium. One channel in the aquarium is bright and the other dark. Crayfish love to live in dark surroundings, and they also love to explore the entire aquarium, including bright places. Of course, they stay longer in the darkness.
