How do octopuses defend themselves from predators?

Octopuses defend themselves using a combination of camouflage, ink clouds, and their ability to squeeze into small spaces. Their skin contains specialised cells called chromatophores, allowing them to change colour and texture to blend into their surroundings. When threatened, they release a cloud of ink to confuse predators and create an opportunity to escape. Their boneless bodies also enable them to hide in crevices that predators cannot reach.
