“…Specifically, these results support findings by Cigliano (1995) and Wada et al (2010) in that some male cephalopods appear to strategically regulate their copulation time based on the mating history of the female, presumably to maximise their reproductive output by balancing both their chance of paternity and their ability to successfully copulate with other females. Sperm competition appears prevalent among cephalopod mating systems (Cigliano, 1995;Hanlon et al, 1999;Naud et al, 2004;Shaw & Sauer, 2004;Wada et al, 2005b;Wada et al, 2006;Buresch et al, 2009;Wada et al, 2010;Iwata et al, 2011;Sato et al, 2013). Future studies using molecular markers might identify correlations between paternity and behavioural patterns including copulation duration and chronology.…”

“…This system can lead to muliple paternity (Morse, 2008;Voight & Feldheim, 2009;Quinteiro et al, 2011). Sperm competition, in the forms of sperm removal, spermloading and mate guarding have been documented amongst male cephalopods (Hanlon et al, 1999;Iwata et al, 2005;Wada et al, 2005b;Wada et al, 2006;Huffard et al, 2008). However, studies investigating the differential time investment that males allocate towards copulating with different females, based on either female novelty or recent mating history of females, are limited (c.f.…”

The southern blue-ringed octopus, Hapalochlaena maculosa (Hoyle, 1883) is a nocturnal species that exhibits a mating system in which females hold sperm from multiple males over a one to two month breeding window before laying a single egg clutch. Contrary to most studied animal mating systems where anisogamy exists, gamete package production is limited for both males and females of this species (~50 spermatophores/eggs). This presents an animal model for studying aspects of sperm competition and dynamic mate choice behaviours. The present study reports on the mating behaviour of H. maculosa observed under laboratory conditions using infrared closed-circuit television video footage. Rates of male copulation attempts increased with male size, while female receptivity to mating attempts increased with female size, resulting in larger animals of both sexes gaining more copulations and spending more time per day in copulation. There was some evidence of female preference of larger males, but no male preference of females based on measured morphological traits. Both sexes terminated copulations in equal frequencies but male-terminated copulations were significantly shorter in duration. Males were more likely to terminate copulation early with females they had previously mated with, however were less likely to do so if the female had recently mated with a different male. Among male-terminated copulations, males mated for longer with females that had previously mated with other males in the trial. Male-male mounts were as common as male-female mounts, suggesting that male H. maculosa are not able to discriminate the sex of conspecifics. These findings suggest male strategic allocation of spermatophores based female mating history is an important factor influencing mating behaviours of this species.ADDITIONAL KEYWORDS: mate choice -Octopus -operational sex ratio -sperm competition.

“…Upon mating, spermatozoa may be stored in paired seminal receptacles of the female's buccal membrane over 4-8 weeks (but also up to 5 months in captivity (Hanlon et al, 1999)), until they are released for egg fertilization (Mangold, 1987). Females have also been shown to mate with multiple males and sperm competition is supposed to be a major feature of reproduction in S. officinalis (Hanlon et al, 1999).…”

Population substructure of the cuttlefish Sepia officinalis (Mollusca: Cephalopoda), as investigated by genetic variation of microsatellite loci, has been reported to be significantly extensive around the Iberian Peninsula with F ST = 0.061 [Pérez-Losada, M., Guerra, A., Carvalho, G.R., Sanjuan, A., Shaw, P.W. So far, reproductive and migration behaviour and in vitro oxygen binding properties of haemocyanin have suggested the existence of separate populations in the English Channel and the Bay of Biscay. Examination of genetic variation at seven microsatellite loci within samples from the Bay of Biscay, the English Channel and the southern North Sea indicated low levels of genetic differentiation in this area but also a breakdown of free gene flow at highly significant average F ST = 0.018. Although there is a considerable genetic exchange between populations of S. officinalis in the English Channel and the Bay of Biscay, they cannot be regarded as a single, freely interbreeding population. Earlier reported biological differences might thus be due to genetic variability between the populations.

“…Most near-shore decapod cephalopods have a promiscuous mating system, and loliginid squids and cuttlefishes show particularly complex reproductive behavior (Hanlon and Messenger 1996). Although the mechanism underlying fertilization in cuttlefishes is far from clear, it likely occurs around the female buccal area (under the mouth), where males deposit their spermatophores (Hanlon and Messenger 1996).…”

Sperm displacement behavior of the cuttlefish Sepia esculenta (Cephalopoda: Sepiidae)

Sperm displacement behavior of cuttlefish (Sepia esculenta) was observed in a tank. Before ejaculation, male cuttlefish used their arms III to scrape out sperm masses attached to the buccal membranes of females. The removed sperm mass debris was directly visible and countable. Active sperm were present within the removed sperm debris, implying that the aim of this behavior is to remove competing male sperm. However, many sperm masses remained on the female buccal membrane even after the removal behavior, showing that sperm removal in S. esculenta is incomplete. The duration of sperm removal (an indicator of male investment in that process) was unaffected by the body sizes of mated pair, the duration of spermatangia placement at the current mating (for the hypothesis that the sperm removal serves to creat attachment space of spermatophores), or the estimated amount of sperm masses deposited from previous matings. Moreover, male S. esculenta performed sperm removal regardless of whether the last male to mate with the partner was himself, suggesting males remove not only the sperm of rivals but also their own. Although the number of removed sperm masses increased with the time spent on removal of sperm, male cuttlefish may shorten the duration of sperm removal to avoid the risk of mating interruption. We conclude that this time restriction would likely influence the degree of partial sperm removal in S. esculenta. A digital video image relating to the article is available at
