>In
females the ink sac is hidden from view by a pair of white nidamental
glands, which lie anterior to the gills. There are also red-spotted
accessory nidamental glands. Both organs are associated with food
manufacture and shells for the eggs. Females also have a large
translucent ovary, situated towards the posterior of the visceral mass.
>Males
do not possess these organs, but instead have a large testis in place
of the ovary, and a spermatophoric gland and sac. In mature males, this
sac may contain spermatophores, which are placed inside the female's
mantle during mating.
>Shallow
water species of the continental shelf and epipelagic/mesopelagic zones
are characterised by the presence of hectocotyli, specially modified
arms used to fertilise the female's eggs.[3] Most deep sea squid lack
hectocotyli and have longer penises; Ancistrocheiridae and Cranchiinae
are exceptions.[3] Giant squid of the genus Architeuthis are unusual in
that they possess both a large penis and modified arm tips, although it
is uncertain whether the latter are used for spermatophore transfer.[3]
Penis elongation has been observed in the deep water species Onykia
ingens; when erect, the penis may be as long as the mantle, head and
arms combined.[3][4] As such, deep water squid have the greatest known
penis length relative to body size of all mobile animals, second in the
entire animal kingdom only to certain sessile barnacles.[3]
TL;DR they have sexu like ningien |
