The functioning of the statocysts of Octopus vulgaris
Proceedings of the Royal Society of London. Series B. Biological Sciences, 1960Abstract Octopuses with both statocysts removed were disorientated when swimming. Only slight disorientations were seen when they walked on horizontal surfaces. Vertical surfaces were sometimes treated as if they were horizontal. Blind octopuses maintained their equilibrium when walking or swimming.

The oxidation of Octopus vulgaris hemocyanin by nitrogen oxides
Biochemistry, 1989The reaction of Octopus vulgaris hemocyanin with nitrite was studied under a variety of conditions in which the green half-met derivative is formed. Analytical evidence shows that the amount of chemically detectable nitrite in various samples of the derivative is not proportional to the cupric copper detected by EPR.

Centrifugal fibers to the retina of Octopus vulgaris
Experimental Neurology, 1966Abstract A modified Glees method has been used to demonstrate degeneration in the retina of Octopus after cutting optic nerves or devascularizing the optic lobe by cutting the optic tract. The massive degeneration considered to be due to damage of a centrifugal pathway reaches a maximum at 1 day after optic nerve section and about 2 1 2 days ...

Breeding season of Octopus vulgaris
Marine Biology, 1972Female Octopus vulgaris Cuvier mated in the laboratory in every month tested. Females maintained in isolation after capture and not mated in the laboratory laid eggs, fertile and infertile, each month of the year. The longest period of sperm viability was 104 days. Young specimens weighing between 4.0 and 66.0 g were found regularly.

Visual habituation in the common octopus (Octopus vulgaris)
2006Non-associative learning is one of the basic manifestations of behavioral flexibility. In order to document this behavioral trait in Octopus vulgaris, we tested the animal's habituation towards a repeatedly presented prey-like visual stimulus. A plastic model of a lobster was presented outside the tank for 15 times for 15 seconds at the beginning of ...
