Read the passage carefully and answer the questions.
The Amazing Octopus
The octopus is one of the most fascinating creatures in the ocean. With eight flexible arms and a soft body, it can squeeze through tiny openings and escape from predators with ease.
One of the octopus's most remarkable abilities is its power to change colour. Its skin contains special cells called chromatophores, which allow it to blend perfectly with its surroundings. Within seconds, an octopus can transform from brown to blue, or display patterns that mimic rocks and coral.
When threatened, the octopus has several defence mechanisms. It can release a cloud of dark ink to confuse its attacker while it makes a quick escape. Some species can even detach an arm if captured, allowing the octopus to flee while the predator is distracted. Amazingly, the lost arm can regrow over time.
Scientists have discovered that octopuses are highly intelligent. In laboratory experiments, they have been observed solving puzzles, opening jars to reach food, and even recognising individual human faces. Some researchers believe that octopuses are among the most intelligent invertebrates on Earth.
Despite their intelligence and adaptability, most octopuses have a relatively short lifespan of just one to two years. After laying eggs, the female octopus dedicates herself entirely to protecting them, often refusing to eat until she dies shortly after the eggs hatch.
