The ear of the octopus can "swim"

Everyone is familiar with the movement of octopus. The powerful wrist foot is their foot for walking on the seabed, and the reaction force formed by their funnel spraying water is also one of their movements. As a member of the octopus family, the octopus is no exception, but unlike its relatives, its ears can "swim".

The octopus swims on the fins like ears. When they swim, the big ears will provide them with the power to move forward. The big ears can flap about 4 to 30 times per second, which is enough for the octopus to walk or hunt in the deep sea.
