Photomicrographs of somatic diploid metaphase plates and karyotypes from three species of octopod gills. A The metaphase plate of O. minor B Karyogram of O. minor from (A) showing the karyotype composition: 42 metacentric (#1–#21), 6 submetacentric (#22–#24), 4 subtelocentric (#25–#26), and 8 telocentric (#27–#30) chromosomes C The metaphase plate of A. fangsiao D Karyogram of A. fangsiao from (C) showing the karyotype composition: 32 metacentric (#1–#16), 16 submetacentric (#17–#24), and 12 telocentric (#25–#30) chromosomes E The metaphase plate of C. chinensis F Karyogram of C. chinensis from (E) showing the karyotype composition: 38 metacentric (#1–#19), 6 submetacentric (#20–#22), 8 subtelocentric (#23–#26), and 8 telocentric (#27–#30) chromosomes. Scale bar 5 μm.
