    This octopus is a common octopus (Octopus vulgaris) The cephalopods (meaning ‘head-footed) are a group of molluscs that contain the octopuses, squid and cuttlefish, and are probably the most intelligent of all invertebrates. They have well-developed heads, with large complex eyes and mouths that feature beak-like jaws. All octopuses have eight tentacle-like arms; indeed ‘octopus.   A common octopus (Octopus vulgaris) can assume a full warning display, changing its color, skin texture and posture, in roughly two seconds. .

In the Catalonian Sea, more particularly in the area of Banyuls and Port Vendres, Octopus vulgaris seems to undergo seasonal migrations, mainly of vertical orientation.

In the early spring, large animals move inshore for spawning. This law explains why O. vulgaris has to alter the amount of water cycled through its mantle cavity as the oxygen concentration in water changes. [3] The gills are in direct contact with water – carrying more oxygen than the blood – that has been brought into the mantle cavity of the : Cephalopoda.

Female 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 days. Young specimens weighing between and g were found regularly.

It is concluded that O. vulgaris breeds throughout the Cited by: Octopuses and cuttlefish also use color change to warn their predators or any animals that threaten them. One of the best examples is the extremely venomous blue-ringed octopus (Hapalochlaena lunulata), which lives in tide pools in the Pacific and Indian Oceans from Japan to : Fox Meyer.

This color-changing ability can also be used to communicate with or warn other octopi. The very venomous blue-ringed octopus becomes bright yellow with blue rings when it is provoked. Octopuses can use muscles in the skin to change the texture of.

When an octopus senses danger, it ejects some "ink". The ink darkens the water, thereby screening the octopus from the other animal. In some species, the saliva—deployed by a beak bite—can also paralyse prey.

Octopuses can travel through water by jet propulsion: they take in water and forcibly eject it through a funnel. Octopus changes color and texture - Eilat - Duration: דמיטרי סלניקובviews.

Octopuses use suckers to anchor the body to the substrate or to grasp, investigate and manipulate objects, just to mention a few of their functions.

Our study focuses on the morphology and adhesion mechanism of suckers in Octopus vulgaris.
