“…In addition to this passive transport, the swimming capacities recorded in the laboratory for planktonic cephalopod hatchlings are within the range or higher than those found for the larval fishes [17–22], which could enhance their dispersal potential. In contrast, mark and recapture experiments with hatchlings of large, benthic cuttlefish, showed limited shallow water dispersal, as the individuals remain in the same or adjacent bays to those in which they hatched [23]. Molecular studies revealed some low-scale geographic population structure in cuttlefish species [24], supporting the suspected low dispersal abilities of this group.…”

Early Mode of Life and Hatchling Size in Cephalopod Molluscs: Influence on the Species Distributional Ranges

et al. 2016

Cephalopods (nautiluses, cuttlefishes, squids and octopuses) exhibit direct development and display two major developmental modes: planktonic and benthic. Planktonic hatchlings are small and go through some degree of morphological changes during the planktonic phase, which can last from days to months, with ocean currents enhancing their dispersal capacity. Benthic hatchlings are usually large, miniature-like adults and have comparatively reduced dispersal potential. We examined the relationship between early developmental mode, hatchling size and species latitudinal distribution range of 110 species hatched in the laboratory, which represent 13% of the total number of live cephalopod species described to date. Results showed that species with planktonic hatchlings reach broader distributional ranges in comparison with species with benthic hatchlings. In addition, squids and octopods follow an inverse relationship between hatchling size and species latitudinal distribution. In both groups, species with smaller hatchlings have broader latitudinal distribution ranges. Thus, squid and octopod species with larger hatchlings have latitudinal distributions of comparatively minor extension. This pattern also emerges when all species are grouped by genus (n = 41), but was not detected for cuttlefishes, a group composed mainly of species with large and benthic hatchlings. However, when hatchling size was compared to adult size, it was observed that the smaller the hatchlings, the broader the latitudinal distributional range of the species for cuttlefishes, squids and octopuses. This was also valid for all cephalopod species with benthic hatchlings pooled together. Hatchling size and associated developmental mode and dispersal potential seem to be main influential factors in determining the distributional range of cephalopods.

“…Sepia latimanus is widely distributed in tropical and warm temperate waters across the Indian and western Pacific Oceans (Dan et al 2012). It is the second biggest cuttlefish after S. apama with a maximum dorsal mantle length of 50 cm and a total weight of 10 kg and become important for fisheries in many countries (Pratasik et al 2015).…”

We describe the complete mitochondrial genome of the broadclub cuttlefish Sepia latimanus, the second largest cuttlefish, collected from the coral waters of Naozhou Island in tropical South China. It is a circular molecule of 16,225 bp in size and consists of 13 protein-coding genes, 2 rRNA genes, 22 tRNA genes, and 1 control region in typical gene arrangement conforming to the vertebrate consensus. The complete mitochondrial genomic sequence of S. latimanus and other 8 species from the same Family Sepiidae were used for phylogenetic analysis and demonstrated that S. latimanus clustered with S. apama, the largest cuttlefish species, and made a separate clade, closely related to the other Sepia and Sepiella species in Family Sepiidae.

“…This results in two overlapping generations variable for size and extent of maturity that due to times of highly skewed operational sex ratios cannot be reproductively separated from one another (Gauvit et al, 1997). A comparable situation may exist in the Bay of Biscay, NW Spain (Guera and Castro, 1988), in S. apama in northern Spencer Gulf (Australia; Hall et al, 2007) and possibly in Sepia latimanus (Dan et al, 2012).…”

“…could make an excellent model for the study of alternative reproductive strategies. Not only would there be many accessible natural replicates (technology now exists to tag and or track cuttlefish in the wild; Bloor et al 2013b, Dan et al, 2012), but the techniques for rearing and experimenting with cuttlefish in captivity are very well known. Additionally, with S. officinalis genome sequencing in progress, we may soon have the tools to learn more about the genetic nature of alternative reproductive strategies and which regions of the genome are under strong selection pressures in this group of animals, which is essential to further our understanding of sexual selection (Neff and Svensson 2013).…”

6Alternative mating tactics (AMTs) are common in the animal kingdom, yet much work 7 remains before their evolution and role in driving sexual selection is fully understood. 8 Utilizing features of citizen science, we present compelling evidence that a third species in 9 the cuttlefish genus Sepia (Cephalopoda) possess males who use sneaky mating and female 10 mimicry as alternative strategies to conspicuous signalling and fighting.. We also present new 11 evidence of large aggregations (n~30) in this species that possibly drive alternative mating 12 strategies. Lastly, we provide footage of an opportunistic sneaky copulation in this species. 13 We believe that alternative mating tactics may be more common in this genus than previously 14 recorded (based on observations presented here and a search of the literature for similar life 15 history, environmental and behavioural factors found in other species within the Sepia 16 genus), and as much of their captive husbandry is well known, they could an ideal system for 17 studying the evolution of alternative reproductive strategies. 18 20 21 22 23 24 25 65 1991), however, a signal may also be received by eavesdroppers who may be able to gain 66 information about the signaller (McGregor, 1993) and their intentions (e.g. court/copulate 67 with a female). A signaller may try and reduce the cost of eavesdropping through tactical 68 deception (Kuczai et al. 2001) i.e. signals may not consistently reveal the genuine status or 69 intentions of the signaller. To be a genuine a case of deception, the receiver of the deception 70 must pay a cost (e.g. Kuczai et al. 2001) and the deceiver must benefit (Byrne and Whitton 71 1992; Hauser 1997).72 73 Another important influence on AMTs is the operational sex ratio (OSR: the ratio of sexually 74 mature males to fertilisable females -Mills and Reynolds, 2003) within a breeding 75 population. If the OSR is skewed towards more males, then this increased competition for 76 females can further drive sexual selection, including AMTs. OSRs are variable between 77 species and even within them from population to population. This variation in the distribution 78 of sexually mature adults may arise from environmental influences on the potential 79 reproductive rates of the sexes (Kvarnemo 1994; Reynolds et al.1986).80 81 1.1 AMTs and cuttlefish 82 Brown et al. (2012) reported an AMT using tactical deception in Sepia plangon (a cuttlefish 83 of the Class Cephalopoda) where males use a 'split' signal. The split signal includes male 84 mating signals (zebra patterning; see Hanlon and Messenger, 1996) on one side of the body 85 (the side towards a female) and a female pattern (e.g. blotched) on the other sidewhich is 86 directed towards a rival male. In certain circumstances, this could allow males to mate with 87 females without alerting other males i.e. a sneak AMT. The authors suggest this strategy 88 deceives a conspecific whilst simultaneously attracting a female (see figure 1, Brown et al. 89 2012). Alternatively, two further studies ...
