Swordtip squid (Uroteuthis edulis) is characterized by a complex population structure and rapid generation renewal and sensitive to habitat changes. Its population growth response to environmental variations implies its flexible life history traits. In this study, with the samples collected in the north‐central waters of the East China Sea from 2017 to 2021, the daily growth of the spring stock was...
The feeding organ of cephalopod species, the beak, can be used to reveal important ecological information. In this study, geometric morphometric approaches were employed to investigate the phylogenetic relevance and classification effect of beak lateral profile shape. The two‐dimensional beak morphologies of 1164 pairs of 24 species from 13 genera and five families were constructed, and their evolutionary...
