The male cuttlefish (Sepia) places the spermatophores in a pocket near the female’s mouth, from which the sperm subsequently make their way to the tubes that carry eggs (oviducts). In no squid studied thus far do either of the sexes…

The spermatophores are complicated, containing sperm reservoir, cement body, cap, and a delicate triggering mechanism for releasing the tube and cementing it to the female’s body, where the sperm…

Once she is positioned over the spermatophore, physical contact with it causes spermatozoa to be ejected into the genital opening (gonopore) of the female. Males that remain…
