Cephalopods are mollusks that are characterized by the great development of the head and the transformation of the foot into tentacles or arms arranged around the head.

These have rows of suction cups on their internal surface that make them extraordinarily prehensile.

They are very well adapted to swimming and move by expelling water through the funnel or siphon they have.

Decapods have an internal limestone shell and octopods lack it.

They are very voracious carnivores.
They have an intestinal gland, the ink sac, which helps them flee from their enemies.
They also have the ability to change color by activating special cells.

Their nervous system is highly developed and they have the most perfected eyes of all invertebrates.
Some have phosphorescent organs.
