Behavioral asymmetries exhibited by the common octopus, Octopus vulgaris, a cephalopod mollusk, during predatory and exploratory responses were investigated. Animals were tested for eye preferences while attacking a natural (live crab) or an artificial (plastic ball) stimulus, and for side preferences while exploring a T-maze in the absence of any specific intra- or extra-maze cues. We found individual-level asymmetry in some animals when faced with either natural or artificial stimuli, but not when exploring the maze. Our findings suggest that visual lateralization in O. vulgaris is context-dependent.

AbstractSpontaneous nerve regeneration in cephalopod molluscs occurs in a relative short time after injury, achieving functional recovery of the lost capacities. In particular, transection of the pallial nerve in the common octopus (Octopus vulgaris) determines loss and subsequent restoring of two functions fundamental for survival, i.e. breathing and skin patterning, the latter involved in communication between animals and concealing. The phenomena occurring after lesion have been investigated in a series of previous studies, but a complete analysis of the changes occurring at the level of the axons and the effects on animals appearance during the whole regenerative process is still missing. Our goal is to determine the course of events following injury. Our goal is to determine the course of events following injury, from impairment to full recovery.We observed nerve regeneration, end-target re-innervation and functional reconnections between central brain and periphery, using the contralateral nerve in the same animal as internal control. The final architecture of the regenerated nervous tissue does not mirror the original structure, however functionality returns to match the phenotype of an intact octopus, and with no visible impact on the behaviour of the animal. This provides exceptional value to these findings for future studies.Summary statementHere we report events occurring after interruption of the peripheral neural circuitry inOctopus vulgaris, from the dramatic loss of normal functioning to full recovery.

<p>The O<em>ctopus vulgaris</em> farming is impaired by the high mortality of the paralarvae during the first month of life. Several factors have been investigated in this regard, but no data exist on the body surface mucus, which represents the interface with the outside environment. This study included morphometric analysis and glycoconjugates characterization of skin mucus in reared <em>Octopus vulgaris</em> paralarvae during the first month of life. Four types of mucous cells were distinguished:  mucous 1 (m1) and mucous 2 (m2) cells were scattered in the mantle epidermis, mucous 3 (m3) and mucous 4 (m4) in the epithelium surrounding the sucker. Except for the presence of fucosylated and neutral glycoconjugates in all mucous cells, each cell type expressed a characteristic glycopattern. m2 and m4 contained also suphate and acid non-sulphate glycans, m3 lacked suphate glycoproteins. Lectin histochemistry showed that mantle mucous cells (m1, m2) expressed GlcNAc and lactosamine terminating glycans. m2 also contained GalNAc terminal or penultimate to sialic acid. m3 was distinguished by mannosylated glycans terminating with lactosamine and m4 by α2,6 sialoglycans. Glycoproteins terminating with lactosamine, Galβ1,3GalNAc, and α1,6-linked fucose were a common feature of paralarvae surface layer. Morphometry revealed a significant decrease of m1 and m2 abundance during the first month of life, afterwards the reared paralarvae died. Since the glycopattern did not change during the investigated period, the mantle mucous cells abundance could be related to the <em>Octopus vulgaris</em> paralarvae survival. </p>
