Octopuses are fascinating creatures. They’re alien, they’re alien-like, and they can be downright creepy. Octopus arms are certainly strange enough as is (and we’re not even talking about their suction cups or tendrils), but it’s the way their bodies fold into themselves that stands out. You’ll never look at your favorite eight-limbed friend in quite the same way again after learning about their anatomy!
Octopuses are extremely intelligent.
Octopuses are very intelligent. They are the only invertebrates to have been shown to use tools, and they can solve puzzles, remember things and use their tentacles to mimic other animals. For example, octopuses have been observed using their webbed arms as paintbrushes when painting walls in aquariums or even on paper.
Octopuses can learn how to open jars or toys quickly by watching others do it before doing it themselves (known as observational learning). If a mollusk such as an armadillo attempts something new but fails at first—perhaps because its owner hasn’t taught them how—it will try again until it succeeds eventually!
They could be the most alien-like creatures on earth.
The octopus is the only invertebrate with a well-developed brain. It has a complex nervous system and it uses its eyes to see in three dimensions, as well as taste through its mouth. The average lifespan of an octopus is one year, although some species can live longer than that.
Octopuses can learn from experience by using their arms and tentacles to explore their environment while they are still young; this allows them to survive when they encounter new things like food or predators. They also have vision because they have more than 300 lenses (lenticular muscles) which help focus light onto photoreceptors located on each eye surface so that it can be processed into electrical signals inside the animal’s brain cells before being transmitted back down through nerves into muscles controlling the movement around its body.”
