Abstract. Every winter thousands of cuttlefish (Sepiaapama Gray) aggregate to spawn along a restricted area of rocky reef in northern Spencer Gulf, South Australia. It is the only known spawning aggregation of cuttlefish in the world and represents an exceptional cuttlefish mating system. Spawning population structure and reproductive behavior were studied quantitatively by underwater visual transects and by focal-animal behavioral sampling with video from April to August 1999. The operational… 
Mating behaviour and general spawning patterns of the southern dumpling squid Euprymna tasmanica (Sepiolidae): a laboratory study
TLDR
It is found that male E. tasmanica increase the number of ‘pumps’ (mantle contractions) when mating with females that had recently mated, showing that males are able to determine the recent mating history of females.
Nocturnal mating behaviour and dynamic male investment of copulation time in the southern blue-ringed octopus, Hapalochlaena maculosa (Cephalopoda: Octopodidae)
TLDR
Male strategic allocation of spermatophores based female mating history is an important factor influencing mating behaviours of this species, suggesting that male H. maculosa are not able to discriminate the sex of conspecifics.
Reproductive Behavior in the Squid Sepioteuthis australis From South Australia: Interactions on the Spawning Grounds
TLDR
Comparison between results and those for other populations of S. australis suggests that behavior may differ from one population to another, and identifies four mating types from 85 separate mating attempts.
Dependance of paternity rates on alternative reproductive behaviors in the squid Loligo bleekeri
TLDR
Multiple mating and multiple paternity in L. bleekeri were found and male competition was more intense between similar-sized males than between different- sized males, but body size did not affect the copulative success in the male-parallel position.
The overlapping reproductive traits of the two male mating types of the oval squid Sepioteuthis lessoniana
TLDR
The overlap in size distributions of the spermatophores and sperms of the male squid implies that medium-sized males may have flexible reproductive strategies, switching between MP and MU mating tactics depending on the context of the mating event and/or female choice.
Effects of commercial fishing on the population structure of spawning southern calamary (Sepioteuthis australis)
TLDR
Investigating population dynamics of Sepioteuthis australis on a fine temporal scale before, during, and after a 3-month commercial fishing closure on the summer inshore spawning grounds of Great Oyster Bay, Tasmania, Australia suggests that increased fishing pressure in recent years may not have reduced the proportion of females.
Using the giant Australian cuttlefish (Sepia apama) mass breeding aggregation to explore the life cycle of dicyemid parasites
TLDR
This study collected giant Australian cuttlefish eggs at different stages of development and filtered seawater samples from the S. apama mass breeding aggregation area and tested these samples for the presence of dicyemid DNA, but did not recover dricemid parasite cytochrome c oxidase subunit I (COI) nucleotide sequences from any of the samples, suggesting eggs are not the stage where new infection occurs.

Female impersonation as an alternative reproductive strategy in giant cuttlefish
TLDR
The observations of giant cuttlefish (Sepia apama) suggest this ability has allowed them to evolve alternative mating strategies in which males can switch between the appearance of a female and that of a male in order to foil the guarding attempts of larger males.
MATING SYSTEMS AND SEXUAL SELECTION IN THE SQUID LOLIGO: HOW MIGHT COMMERCIAL FISHING ON SPAWNING SQUIDS AFFECT THEM?
TLDR
An approach to studying reproductive behavior in the context of fisheries management is outlined, and features of the mating system of Loligo opulercens that should be understood before high levels of exploitation are permitted are speculated.
Sperm competition in horseshoe crabs (Limulus polyphemus)
TLDR
A paternity analysis was conducted to determine the proportion of eggs fertilized by attached and satellite males in horseshoe crabs and found high variability in the success of satellite males, ranging from 0 to 88%.

TLDR
While knowledge about the breeding of Atlantic salmon is detailed, it is only beginning to understand the ultimate causes and/or functional significances of their reproductive strategies, and predictive models of the life history variation are developing, focusing on the need for empirical study and testing of life history and reproductive patterns.
Flexible reproductive strategies in the squid Loligo forbesi
TLDR
Two size modes at maturity were found in both sexes, but separation into size cohorts was more pronounced in males than in females, and preliminary ageing studies suggest that these size modes are not due to different age groups at breeding.
Male rank, female breeding synchrony, and patterns of paternity in the boat-tailed grackle
TLDR
The results suggest that male and female behavior in female-defense polygyny results from complex coevolution of the sexes in the boat-tailed grackle.
Effects of Crowding on the Social Behavior of Cuttlefish (Sepia officinalis).
TLDR
Analysis of results indicated that behavior was strongly affected by housing conditions and suggested that this species is probably semi-solitary in natural conditions.
Disruptive selection for alternative life histories in salmon
TLDR
Age of maturity in salmon has probably not evolved as a single optimum, but rather as a ‘mixed evolutionarily stable strategy13,14 in which precocious maturity is an evolutionarily viable alternative life history strategy.
Cephalopod diet of the Australian fur seal: Variation due to location, season and sample type
TLDR
The size range and species composition of the diet varied according to the sample types, with faeces containing only small beaks relative to regurgitates and stomachs, and errors associated with sample types and application of regression equations are discussed.
