Invertebrates are a very diverse group of animals, showing a wide spectrum of life strategies and adaptations. They often exhibit very complex behavioural and social patterns. In crayfish, the largest freshwater invertebrates, we found a new behavioural pattern, burying their own exuviae after moulting. Such a pattern may be an as yet unrecognized type of hoarding or caching. The buried exuvia is exhumed after 2 or 3 days (when the crayfish body is no longer as soft) and consumed. This behaviour is probably self-protective (hiding the mark of a helpless prey), as well as having mineral storage reasons. Such complex behavioural patterns in invertebrates present new challenges for future research.
无脊椎动物是种类非常多样的动物群体，展现出广泛的生存策略和适应性。它们常常表现出非常复杂的行为和社会模式。在小龙虾（最大的淡水无脊椎动物）中，我们发现了一种新的行为模式，即蜕壳后掩埋自己的蜕壳。这种模式可能是一种尚未被认识的贮藏或藏匿类型。被掩埋的蜕壳在2或3天后（当小龙虾身体不再那么柔软时）被挖出并吃掉。这种行为可能既有自我保护的作用（隐藏无助猎物的标记），也有矿物质储存的原因。无脊椎动物中如此复杂的行为模式给未来的研究带来了新的挑战。
