摘　　要：With the decline of traditional world economic fisheries resources,the exploitation and utilization of cephalopod resources have been recognized generally in the world and many researches on cephalopod resources and biology were made.Beak with the features of steady structure,erosion-resistant and better information storing,is one of hard and main predation organs of cephalopods,and it not only plays an important role in taxonomy but also as a good material to study cephalopod biology and taxonomy.Based on the studies conducted by the authors at home and abroad,the paper described the morphological characteristics of beak and the studies of beaks were reviewed,which were applied in cephalopod biology,taxonomy,stock estimation and feeding habits of predators.The results show that the fixed term "beak" has been formed in the morphology,and has played an important role in cephalopod taxonomy.A new approach on analyzing food composition and diet change was also provided by the analysis of pigmentation in the beak,and analyzing pigmentation has become one of the key problems in studying age and growth of cephalopod.The results show that some problems still exist in age identifying and stock estimating,which should be solved in the future,although certain progress has been made.With the decline of traditional world economic fisheries resources, the exploitation and utilization of cephalopod resources have been recognized generally in the world and many researches on cephalopod resources and biology were made.

Based on the studies conducted by the authors at home and abroad, the paper described the morphological characteristics of beak and the studies of beaks were reviewed, which were applied in cephalopod biology, taxonomy, stock estimation and feeding habits of predators. The results show that the fixed term ＂beak＂ has been formed in the morphology, and has played an important role in cephalopod taxonomy. A new approach on analyzing food composition and diet change was also provided by the analysis of pigmentation in the beak, and analyzing pigmentation has become one of the key problems in studying age and growth of cephalopod. The results show that some problems still exist in age identifying and stock estimating, which should be solved in the future, although certain progress has been made.
