How does an octopus propel itself through the water?

Answer 1

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.

Answer 2

It tentic

Though an octopus may move over the ocean floor using its tenticles, if startled it will force water through its syphon and jet away, often leaving a cloud of black ink (highly concentrated melanin) to confuse an enermy.
