Interesting about the octopus

  • The words octopus, octopus and octopus are often used synonymously. For precise delimitation: octopuses belong to the subgroup of squid. The word octopus can be used synonymously with octopus.
  • The squid can move each of its eight arms independently. An autonomous-working nerve node sits in each of the arms.
  • In case of danger, the octopus ejects a brown-blue cloud. With the ink cloud, the squid tries to distract his predator from himself.
  • The dye of the octopus was formerly used as ink. Today, this dye is used only for coloring foods (e.g., noodles).
  • Cuttlefish can adapt the color and structure of the skin to the environment.
  • Octopuses are among the most intelligent animals in the ocean. Kraken demonstrated remarkable learning skills in experiments. However, octopuses do not grow very old (on average three years), which significantly limits their progress.
  • The movement of the squid works through the so-called recoil principle: water is first drawn into the mantle cavity, and then ejected jerkily again. With the thrust thus generated considerable speeds can be achieved at least in the short term.
  • Octopuses have no solid skeleton and can therefore hatch through enormously small openings (diameter less than 2cm).
  • Because of their short lifetime, squid females only once come to lay their eggs (more than 300,000 eggs possible).
  • Squid, closer relatives of squid, reach a weight of approximately 450kg.
