lessoniana behavior during mating seasons in two distant geographical locations, and found new behavioral elements in the sexual courtship of S. However, to date it has not been the focus of detailed behavioral research in the wild. sepioidea, is a group-living species that forms shoals and/or schools, and exhibits complex social and sexual behaviors (Moynihan and Rodaniche 1982, Boal and Gonzalez 1998, Sugimoto and Ikeda 2012), including the presence of sneaker males or ‘female mimics’ (Wada et al. The bigfin reef squid Sepioteuthis lessoniana, like the closely related S. Indeed, literature on coastal squids has described mate-guarding as the pre- and post-copulatory role of males, who are generally observed positioned around the female while she lays eggs in crevices, exhibiting agonistic displays to ward-off rivals to prevent insemination by other males’ sperm (Moynihan and Rodaniche 1982, Mather 2016, Hanlon and Messenger 2018, Morse and Huffard 2019). Therefore, given the diverse number of tactics used to both attract a mate and deter competitors, effective female mate-guarding by consorting males is critical to reproductive success in group-mating cephalopod species. Moreover, males can simultaneously exhibit receptive color patterns to females and agonistic patterns or even deceptive female patterns to rival males (Brown et al.
#GROUP OF SQUIDS SKIN#
Through dynamic skin patterning accompanied by typical body postures, individuals send visual signals in the form of displays to potential mates and rival competitors, often engaging in escalating conflicts (Moynihan and Rodaniche 1982, Mather 2016). Cephalopods that mate in groups, in particular coastal squid and cuttlefish species, have evolved complex sexual tactics to maximize reproductive success (Morse and Huffard 2019). Fitness is defined by the successful passing of an individual’s genes to the next generation.
