Life habits of octopus
In order to avoid being killed by predators, American scientists have discovered a "high IQ" octopus that can escape by walking on two feet in the Indian Ocean, in addition to the well-known mimicry camouflage and wrist protection technology.
Christine Huffard of the University of California, Berkeley and her team photographed an octopus named Maginettes in Indonesian tropical waters, which is about the size of an apple. When facing danger or encountering divers, this octopus will bend and fold up six of its eight claws to make a coconut shell.
The remaining two "claws" will stand on the bottom of the sea and secretly move backwards, like a small coconut that moves, striding backwards to escape, with a very funny posture.
