Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish 总被引:1,自引:0,他引:1
Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific
signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females
displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males,
prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce
agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors
suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to
human observers.
