Generally less actively swimming than their fellow cephalopods [[squid]] and [[cuttlefish]], octopi have eight suckered [[tentacle]]s used for attachment to rocks and to prey. To move, it may pull itself over the sea bed with its tentacles, but when in a hurry, it shoots a jet of water out of its body, thrusting it through the water.
