The new information reported in this paper is based on 11 specimens of the large-tuberculate octopus Graneledone macrotyla . These specimens were caught in bottom trawl surveys ATLANTIS 2009 and 2010 carried out on the Patagonian slope off the Argentinean Economic Exclusive Zone between 24 February and 1 April 2009 and from 9 March to 5 April 2010 respectively. A new diagnosis and a complete description of the species are provided. This is the first time that stylets, beaks and spermatophores… 
On gonadic maturation and reproductive strategy in deep-sea benthic octopus Graneledone macrotyla
TLDR
The large- tuberculate octopus Graneledone macrotyla showed a group-synchronous ovulation pattern, regulative atresia, and a batching spawning pattern with a few egg batches spawned inter- mittently over an extended period of spawning.
On gonadic maturation and reproductive strategy in deep-sea benthic octopus Graneledone macrotyla
TLDR
The large-tuberculate octopus Graneledone macrotyla showed a group-synchronous ovulation pattern, regulative atresia, and a batching spawning pattern with a few egg batches spawned intermittently over an extended period of spawning.
Reproductive strategy of deep-sea and Antarctic octopods of the genera Graneledone, Adelieledone and Muusoctopus (Mollusca: Cephalopoda)
TLDR
It is demonstrated that the size distribu- tion of post-ovulatory follicles (POF) is mostly unimodal, suggesting that they only lay 1 batch of eggs, and that deep-sea and polar benthic octopods are generally not multiple spawners.
Reproduction in rare bathyal octopods Pteroctopus tetracirrhus and Scaeurgus unicirrhus (Cephalopoda: Octopoda) in the east Mediterranean as an apparent response to extremely oligotrophic deep seas
TLDR
Both species were found to exhibit a reproductive tactics of producing eggs much larger than in the western part of the sea which likely results in larger hatchlings with higher viability.
Oviducal glands throughout the gonad development stages: a case study of Octopus mimus (Cephalopoda)
TLDR
Structural changes of each section of the ODG of Octopus mimus are described histologically throughout the gonad development stages (GDS), which complements the GDS and provides better reproductive status assessment.
Towards species identification of the bathyal octopod Graneledone (Mollusca: Cephalopoda)
TLDR
Wart distribution may effectively distinguish species throughout the genus Graneledone, accomplishing the necessary first step in furthering the knowledge of deep-sea biodiversity and reconstructing phylogenetic relationships.
Morphological and histological description of the reproductive system of Octopus hubbsorum (Mollusca: Cephalopoda)
TLDR
Detailed morphological and histological descriptions of male and female reproductive systems of O. hubbsorum are provided, locating and characterizing each of their constituent parts.
Tactical Tentacles: New Insights on the Processes of Sexual Selection Among the Cephalopoda
TLDR
It is concluded that sperm competition and possibly cryptic female choice are likely to be critical determinants of which individuals' alleles get transferred to subsequent generations in cephalopod mating systems.
Effects of inter-annual temperature variability, including ENSO and post-ENSO events, on reproductive traits in the tunicate Pyura praeputialis
TLDR
It is concluded that future thermal anomalies or projected global average sea surface warming associated with climate change might have no negative consequences on these reproductive traits of P. praeputialis, which suggests this species is ecologically resilient and that the ecosystem services that this species provides for other invertebrate and algal species will be maintained.

OOGENESIS AND GONAD DEVELOPMENT IN THE COLD WATER LOLIGINID SQUID LOLIGO GAHI (CEPHALOPODA: MYOPSIDA) ON THE FALKLAND SHELF
TLDR
It was shown that the process of the oocyte development in the gonad and number of oogenetic stages in L. gahi are similar to those described before in a number of temperate loliginid species, however, development of both yolkless and vitellogenic oocytes is shifted to the earlier stages of the reproductive system maturation.

  • 2006
TLDR
The examination of five females of the deep-benthic octopus Graneledone pacifica showed that their developing oocyte size-distribution was normal in two specimens at an early maturation stage, bimodal in three specimens at a more advanced stage, and three-modal in the farthest advanced stage specimen.

TLDR
Four Benthoctopus species are recognized in the waters of the Falkland Islands and the hatchlings possess arms that are much longer than mantle length with a large number of suckers, and do not have discernible chromatophores.
