Amazing Facts

  • Octopuses have rounded bodies, bulging eyes, and eight long arms that make them stand out in the water. They can be found in all of the world’s oceans, but they are particularly common in warm, tropical waters.
  • While some species of octopuses are pelagic, meaning they live near the water’s surface, the majority of octopuses live on the ocean floor. Other octopus species live in deep, dark waters, emerging from underneath the surface at dawn and dusk to hunt for food.
  • Octopuses can also change colour to interact with their fellow octopuses. Octopuses are solitary creatures that live alone in rock dens, which the octopus constructs with its powerful arms.
  • An octopus will release a cloud of black ink when it is detected, obscuring its attacker’s vision and allowing it time to swim away. The ink also contains a material that dulls a predator’s sense of smell, making it more difficult to track down the escaping octopus.
  • Hundreds of suckers line the octopus’ limbs, each of which can move independently thanks to a complex bundle of neurons that serves as a brain, allowing the animal to touch, smell, and control objects. Octopuses can open clamshells, move rocks, and even dismantle aquarium filtration systems.
  • Octopuses have two sexes, and the male has a modified arm called a hectocotylus that it uses to inject spermatophores, or packets of sperm, directly into the female’s mantle cavity. During the winter, O. vulgaris mates, and the eggs, which are about 0.3 cm (1/8 inch) long, are laid under rocks or in holes, with a total number of eggs exceeding 100,000.
  • The female guards the eggs for the four to eight weeks it takes for the larvae to hatch, cleaning them with her suckers and agitating them with water. The tiny octopods, which look very similar to their parents when they hatch, spend several weeks drifting in the plankton before settling on the bottom.
