Joe McCormick: 我对鹦鹉鱼的黏液茧非常感兴趣。我查阅了大量资料，发现鹦鹉鱼在睡觉时会制造黏液茧，这种黏液茧是一种透明的胶状物质，可以保护它们免受捕食者的侵害。不过，最新的研究表明，黏液茧的主要作用是防止寄生虫的攻击，特别是那些吸血的等足类动物。虽然制造黏液茧需要消耗一定的能量，但与避免寄生虫带来的危害相比，这是非常值得的。此外，我还了解到，鹦鹉鱼可能会在早上吃掉自己的黏液茧，以回收其中的能量。 Robert Lamb: 我认为黏液茧的功能非常有趣。最初，我们认为它可能是一种防御机制，用来保护鹦鹉鱼免受大型捕食者的侵害。但实际上，它更像是一个蚊帐，用来防止微小的寄生虫叮咬。这种保护机制对于鹦鹉鱼来说非常重要，因为这些寄生虫可能会传播疾病。总的来说，黏液茧是鹦鹉鱼适应环境的一种非常聪明的策略。
