How is an octopus able to fit his entire body into any space in any regardless of that space?

An octopus can fit its entire body into tight spaces due to its unique anatomy. It has a soft, malleable body without any rigid bones, allowing it to squeeze through small openings. Additionally, its beak is the only hard part, and as long as the opening is larger than its beak, the octopus can contort and maneuver its body to fit through. This adaptability is a key survival trait, enabling it to escape predators and access concealed habitats.
