An octopus propels itself through the water primarily by jet propulsion. It draws water into its mantle cavity and then rapidly expels it through a siphon, creating thrust that propels the octopus in the opposite direction. This form of locomotion allows octopuses to move quickly and efficiently in their aquatic environment.
a siphon
by propulsion. the propel themselves through the water if you ride the Kraken you'd know.
a dolphin gets around by using its tail and flippers to propel itself through the water.
A jellyfish moves through the water by contracting and relaxing its bell-shaped body, pushing water behind it to propel itself forward.
Octopus do not have fins. They swim by using their arms and body. If they need to go very fast, they squirt water out of their siphon and use "jet propulsion." Mostly, an octopus will just crawl around on the bottom to get around. Some Octopus do have ear like appendage's with which the use to propel themselves through the water also. They are also refereed to as Dumbo Octopus.
It sucks in water and then pushes it out to propel itself.
The opposite direction of the water it moved.
With the tail. useing his tail moving it back and forth he also sways his body a little
Well Octopuses don't squirt out water from themselves, they propel they're tentacles from an open position downward which acts like a rocket and propels the octopus forward.
It uses its 8 tentacles and thrashes them to propel through the water, like if you swam moving your arms to the sides
A jellyfish swims by contracting and relaxing its bell-shaped body, pushing water out to propel itself forward. This movement is called pulsing, and allows the jellyfish to move through the water.
It spins to move through the water
