摘要

用切头法对7只头足类动物的胚胎进行了核生物学研究。2种Sepia esculenta和Sepia lycidas, 3种oligoligo Sepioteuthis lessoniana, Heterololigo bleekeri和Photololigo dulits均为2n = 92)。他们的核型和染色体总长度彼此略有不同。两种章鱼(ocellatus和O. vulgaris)均为2n=60。然而，它们的核型和染色体的总长度却截然不同。

Karyological Studies on Seven Cephalopods

Karyological studies were made on the embryos of seven cephalopods using chopping method. Two sepiids (Sepia esculenta and Sepia lycidas) and three loliginids (Sepioteuthis lessoniana, Heterololigo bleekeri and Photololigo edulits) were all 2n = 92). Their karyotypes and total length of chromosomes were slightly different from each other. Two octopuses (Octopus ocellatus and O. vulgaris) were both 2n=60. Their karyotypes and total length of chromosomes were, however, remarkably different from each other.
