Abstract: | The external structure of postorbital organ is described in detail in seven representatives of family Astronesthidae, i.e., Borostomias elucens, B. panamensis, B. mononema, B. antarcticus, Heterophorus ophistoma, Neonesthes microcephalus, and Rhadinesthes decimus. The shape, sizes, position with respect to eye, and some other features of the structure of the postorbital organ are characteristic of the species or close species. The comparison of the structure of this organ in the above-mentioned representatives of the family Astronesthidae and earlier studied species of genus Astronesthes is given. |
