Female reproductive features have been investigated in five polar and deep-sea bobtail squid genera Rossia and Neorossia (R. macrosoma, R. moelleri, R. pacifica, N.c. caroli and N.c. jeannae). These species are characterized by asynchronous ovary maturation, very large eggs (>10% ML), fecundity of several hundred oocytes, very high reproductive output, and continuous spawning with low batch fecundity. This adaptive complex of reproductive traits evolved in these small animals as an optimum… 
Reproductive Biology of the Bobtail Squid Rossia macrosoma (Cephalopoda: Sepiolidea) from the Eastern Mediterranean
TLDR
Rossia macrosoma was investigated based on material collected from the eastern Mediterranean Sea, to determine potential fecundity, reproductive strategies and size at maturity, and according to egg diameter distributions in gonads, R. macrosoma has asynchronous ovary maturation, spawning more than once.
Reproductive biology of the lentil bobtail squid, Rondeletiola minor (Cephalopoda: Sepiolidae) from the eastern Mediterranean
TLDR
A total of 208 Rondeletiola minor were sampled from the eastern Mediterranean with the depth contours of 150, 350 and 550 m, and the life cycle of R. minor was estimated to be 10 months with different cohorts in reproduction depending on how temperature affects the hatching.
Reproduction of the Atlantic bobtail squid Sepiola atlantica (Cephalopoda: Sepiolidae) in northwest Spain
TLDR
Females of S. atlantica have group-synchronous ovary maturation, with a positive correlation between female mantle length and ripe oocyte mass, suggesting a terminal investment strategy.
Reproductive biology of Neorossia caroli (Cephalopoda: Sepiolidae) in the Aegean Sea
TLDR
It has been observed that the pattern of ovulation of N. caroli is asynchronous and that spawning is continuous and that females appeared to reach larger sizes than males.
Reproductive Biology of Sepiola intermedia (Sepiolidae: Cephalopoda) in the Aegean Sea, Eastern Mediterranean
TLDR
This study provides new records on the reproductive biology of S. intermedia from the Aegean Sea and determines potential fecundity ranges for females and males to be between 148-406 eggs and 54-383 spermatophores.
Fecundity, oogenesis, and ovulation pattern of southern African Lycoteuthis lorigera (Steenstrup, 1875)
TLDR
The ovulation pattern of L. lorigera is asynchronous, which indicates a spawning strategy where batches of eggs are spawned repeatedly over time, and the reproductive strategies of oceanic squid inhabiting the continental slope of southern Africa are discussed and compared.
Distribution, abundance, reproduction and ageing of the common bobtail squid Sepietta oweniana (Sepiolidae, Cephalopoda) from the Portuguese Coast
TLDR
The year-round presence of mature animals, asynchronous ovulation, the presence of maturity specimens over a range of different sizes and the occurrence of feeding activity throughout spawning are indicative of a continuous spawning strategy in this species.
Ovarian development in Argentinean shortfin squid Illex argentinus: group-synchrony for corroboration of intermittent spawning strategy
Modern living cephalopod species have evolved a wide phenotypic diversity and flexibility of reproductive strategies, which is closely linked to the pattern of oogenesis and oocytes ovulation of
On the spermatophore implantation in bobtail squid Rossia macrosoma (Cephalopoda: Mollusca)
TLDR
In this study, mated female specimens of Rossia macrosoma from the Aegean Sea were examined and spermatangia could be implanted in females’ tissue autonomously by major role of the spiral filament located on the oral part of sperMatangia.

Fecundity of the common cuttlefish, Sepia officinalis L. (Cephalopoda, Sepiidae): a new look at an old problem*
TLDR
Regulative oocyte resorption was observed at early maturation in some cuttlefishes, showing that intermittent spawning, which occurs in captivity, is a normal process in natural habitats.

TLDR
It was observed that the spawning period of S. oweniana covers the whole year with two maxima in April-May and October-November, and no discernible difference in length frequencies of males and females was observed.

TLDR
Results indicate that S. pteropus is a typical representative of the epipelagic oceanic cephalopod reproductive strategy characterised by small eggs, high fecundity, long intermittent spawning, active feeding, and somatic growth during spawning.

TLDR
Ovary maturation in mature female L. vulgaris was similar to that observed in other loliginid squid, when small protoplasmic oocytes predominate throughout the life cycle.
