“…All tanks were supplied with running oxygenated seawater at 17±1°C. After hatching, the animals were housed in groups and provided with enriched habitats, which increases cuttlefish growth rates, has a positive effect on juveniles' learning abilities (Dickel et al, 2000) and improves the richness of their behavioral repertoire (Poirier et al, 2004;Poirier et al, 2005). Animals were fed daily with live shrimp (Crangon crangon) of suitable size.…”

SUMMARYPolarization sensitivity is a characteristic of the visual system of cephalopods. It has been well documented in adult cuttlefish, which use polarization sensitivity in a large range of tasks such as communication, orientation and predation. Because cuttlefish do not benefit from parental care, their visual system (including the ability to detect motion) must be efficient from hatching to enable them to detect prey or predators. We studied the maturation and functionality of polarization sensitivity in newly hatched cuttlefish. In a first experiment, we examined the response of juvenile cuttlefish from hatching to the age of 1month towards a moving, vertically oriented grating (contrasting and polarized stripes) using an optomotor response apparatus. Cuttlefish showed differences in maturation of polarization versus luminance contrast motion detection. In a second experiment, we examined the involvement of polarization information in prey preference and detection in cuttlefish of the same age. Cuttlefish preferentially chose not to attack transparent prey whose polarization contrast had been removed with a depolarizing filter. Performances of prey detection based on luminance contrast improved with age. Polarization contrast can help cuttlefish detect transparent prey. Our results suggest that polarization is not a simple modulation of luminance information, but rather that it is processed as a distinct channel of visual information. Both luminance and polarization sensitivity are functional, though not fully matured, in newly hatched cuttlefish and seem to help in prey detection. Supplementary material available online at

“…For example, many of the early juveniles show a relatively inappropriate body pattern such as, for example, a disruptive pattern (pattern which 'breaks' the natural outline of the body) on a uniform substrate [Hanlon and Messenger, 1988]. Besides, maturation of the body patterning (diversification and high efficiency to cope with ecological demands) during the first 2 months of postembryonic life has been reported [Hanlon and Messenger, 1988;Poirier et al, 2005]. OT-like immunoreactive fibers in the chromatophore lobes are present from birth, and their maturation is completed at day 30.…”

“…The activity of chromatophores is directly controlled by the anterior and posterior chromatophore lobes [Young, 1977]. Newborn cuttlefish are able to display body patterns which seem to be stereotyped [Poirier et al, 2005]. For example, many of the early juveniles show a relatively inappropriate body pattern such as, for example, a disruptive pattern (pattern which 'breaks' the natural outline of the body) on a uniform substrate [Hanlon and Messenger, 1988].…”

“…All these complex processes require behavioral plasticity. In the last decades, the ontogenesis of behavioral and neural plasticity in the cuttlefish has been the subject of detailed studies [Messenger, 1973;Dickel et al, 1997Dickel et al, , 2001Dickel et al, , 2006Agin et al, 1998;2006b;Darmaillacq et al, 2004;Poirier et al, 2004Poirier et al, , 2005. In the early juveniles, learning abilities are poor and defensive strategies appear relatively stereotyped.…”

In vertebrate species, the neuropeptide oxytocin (OT) has been implicated in neural and behavioral development. Although several OT-like peptides have been characterized in invertebrate species, the ontogenesis of the OT-like system has not yet been described in these species. Thus, the aim of the present study was to perform an immunohistochemical investigation of the spatiotemporal distribution of OT-like elements in the central nervous system (CNS) of a decapod cephalopod mollusc, the cuttlefish, Sepia officinalis, during the first 3 months of postembryonic development. On the day of birth, OT-like immunoreactivity was detected throughout the whole CNS. Some nervous structures (e.g. the magnocellular lobes) exhibited a stained pattern in newborns similar to that reported in our previous study in adult cuttlefish whereas other lobes (e.g. the vertical lobe complex) showed maturation during the first weeks of life. Finally, at the age of 60 days, the general pattern of staining in the CNS was comparable to the adult distribution. The putative roles of the OT-like system with regard to the development of some behaviors in juvenile cuttlefish are discussed. The present study provides a neurochemical basis for the investigation of postnatal development of complex behaviors in cephalopods and suggests, for the first time in an invertebrate species, important organizational effects for the OT-like system in the course of the first weeks of life.

“…They are able to match the visual characteristics of their environment with speed and complexity from hatching via chromatophores that are under direct neural control [17][18][19][20][21]. The animals make decisions about what body pattern should be used in a given visual environment by integrating cues about local and global visual characteristics such as contrast, overall illumination and texture, thereby offering a unique insight to non-human visual perception [22][23][24][25][26][27].…”

Visual interpolation for contour completion by the European cuttlefish (Sepia officinalis) and its use in dynamic camouflage

Cuttlefish rapidly change their appearance in order to camouflage on a given background in response to visual parameters, giving us access to their visual perception. Recently, it was shown that isolated edge information is sufficient to elicit a body pattern very similar to that used when a whole object is present. Here, we examined contour completion in cuttlefish by assaying body pattern responses to artificial backgrounds of 'objects' formed from fragmented circles, these same fragments rotated on their axis, and with the fragments scattered over the background, as well as positive (full circles) and negative (homogenous background) controls. The animals displayed similar responses to the full and fragmented circles, but used a different body pattern in response to the rotated and scattered fragments. This suggests that they completed the broken circles and recognized them as whole objects, whereas rotated and scattered fragments were instead interpreted as small, individual objects in their own right. We discuss our findings in the context of achieving accurate camouflage in the benthic shallow-water environment.
