Rhynchoteuthion larvae of Ommastrephid squids of the western North Atlantic with the 1St description of larvae and juveniles of illex-illecebrosus
The larvae and juveniles of Illex illecebrosus (Ommastrephidae) are described for the first time based on specimens from the western North Atlantic off Cape Hatteras northward to Georges Bank, New England. Two other larval forms of ommastrephid squids, Rhynchoteuthion larvae, are recognized and tent...

| Summary: | The larvae and juveniles of Illex illecebrosus (Ommastrephidae) are described for the first time based on specimens from the western North Atlantic off Cape Hatteras northward to Georges Bank, New England. Two other larval forms of ommastrephid squids, Rhynchoteuthion larvae, are recognized and tentatively identified with Ommastrephes and Ornithoteuthis. Larvae and juveniles of Illex were captured during all 'seasons, indicating that spawning takes place over an extended period, possibly yearround, when the broad geographical range of the species is considered. Localities of capture of smallest larvae ( 1.5 mm mantle length) indicate that the spawning site of Illex illecebrosus lies along the outer edge of the continental shelf. |
