Observations on mating, egg-laying and hatching of aquarium-held individuals of Octopus tetricus Gould, 1852 are described. Females were able to store viable spermatozoa for periods up to 114 days, and laid many small eggs in strings 10 to 12 cm long. The duration of embryonic development varied inversely with temperature. The newly hatched planktonic larvae were 2.5 mm long by 1.1 mm wide, but attempts to rear them were unsuccessful, the longest survival being 21 days. The females died… 

Embryonic development in Octopus aegina Gray, 1849

TLDR
Development stages of the embryo were sequenced based on morphological characters and the new born resembles adults in form except for its free-swimming mode of life.

Life cycle of the marbled octopus, Amphioctopus aegina (Gray) (Cephalopoda: Octopodidae) reared in the laboratory

TLDR
Overall similarities in these cephalopod taxa attest to the fitness of a life-history strategy involving production of planktonic offspring from benthic adults.

Biology of the planktonic stages of benthic octopuses

TLDR
Most of the understanding of octopus paralarvae comes from studies of just two species (Octopus vulgaris and Enteroctopus dofleini) and knowledge of the vast majority of benthic octopus species with planktonic stages is considered rudimentary or non-existent.

Egg laying and embryo development of Octopus huttoni in response to temperature and season

TLDR
Reproduction was found to occur all year-round, but there was a tendency to lay eggs in the spring and summer, most likely due to the increase in planktonic food production during this time of year.

TLDR
Increase in mean ovary index and mean values for egg size are strongly seasonal and indicate a peak incidence of sexual maturity over 2–3 months in the July-September period.

EMBRYONIC DEVELOPMENT OF AMPHIOCTOPUS MARGINATUS (TAKI) (MOLLUSCA: OCTOPODIDAE) IN CAPTIVITY

Octopuses, represented by over 300 species are the cephalopod molluscs inhabiting primarily tropical waters of the world. They are solitary invertebrates with little documentation of their response

NOTES ON THE LABORATORY CULTURE OF THE OCTOPUS LARVAE

The larvae of the Japanese commercial octopod, Octopus (Octopus) vulgare CUVIER, were successfully reared from the swimming larvae just after hatching to the benthic young octopus in 33 to 40 days on

Breeding season of Octopus vulgaris

TLDR
It is concluded that O. vulgaris breeds throughout the year, at least in Bahamian waters.

The problems of reproduction of Octopus vulgaris and the seasonal distribution in the sea of planktonic larvae, benthonic juveniles and adults are discussed. The influence of environmental factors on

Ventilation rate and copulation in Octopus vulgaris

TLDR
Observation of arching and pumping movements of the male as well as measurements of its ventilation rate before and during copulation indicate that only a few spermatophores are transferred per copulation.
