Stages;Females;Males Juvenile;"Reproductive system unrecognizable";"Reproductive system unrecognizable" "A – Immature";"Nidamental glands distinguishable under dissection microscope. The ovary is small and filiform, and lacks a granulose structure";"Spermatoforic organ and sac very small and distinguishable only under dissection microscope. The spermatoforic sac lacks spermatophores and testis resemble a thin membrane or a small lobule" "B – In maturation";"Nidamental glands small to large in size. Early stages differs from stage A by a bulged ovary with a clearly granulose structure containing small oocytes or ovules. Latter stages differ from stage C by an opaque whitish ovary with a reticular system on the walls of oocytes and ovules (particularly evident in Doryteuthissanpaulensis and Lolligunculabrevis)";"There are few and small spermatophores in the spermatoforic sac, the testis is clearly distinguishable to the naked eye" "C – Mature";"Ovary and oviduct full of oocytes, occupying half of the posterior mantle cavity. Nidamental glands swollen and firm. All or most ovules amber in color, semi-transparent, and lacking a reticular system. Mature ovules filling the oviduct, but in some females they may also fill the ovary";"Spermatoforic sac full of completely developed spermatophores. Testis at its largest size. When males mature, they produce spermatophores continuously, making it difficult to tell them apart from spent individuals" "D – Spent";"Large females with flaccid or reduced nidamental glands. Ovary and oviduct flabby with few or no mature ovules, but with some immature ovules and tissue remain";–
