Nothing is known about the mating system or mating behavior of this species.
What little is known about reproduction in Stauroteuthis syrtensis has been has been determined by examining preserved specimens.The male genital system consists of testis, vas deferens, needhams sac, accessory gland, and terminal organ. The seminal vesicle is packed with about 100 spermatophores each with a length of 1-2mm.
The female genitalia are unpaired and consist of a single oviduct (with both proximal and distal portions) and an oviducal gland. The majority of the eggs were less than 1mm, but the largest found were in upwards of 11mm. This larger egg size suggests a more developed maturation stage. The ovary contained about 900 eggs. Eggs were also found in the proximal oviduct maybe ready for fertilization.
Breeding interval: Breeding interval unknown.
Breeding season: Breeding season unknown.
Range number of offspring: 900 (high) .
Key Reproductive Features: gonochoric/gonochoristic/dioecious (sexes separate); sexual ; fertilization (Internal ); oviparous
Because no juvenile specimens have been found, little is known about the parental care of these species.
Parental Investment: pre-fertilization (Provisioning, Protecting: Female)
