The image shows an octopus inside the shell of
a sea snail, which appears to be a pufferfish shell. The octopus is visible with its arms spread out and tentacles surrounding it. It's resting in what seems to be
a natural environment, possibly underwater as suggested by the sandy floor and the blue coloration at the bottom. This scene illustrates
a symbiotic relationship where the octopus provides protection from predators by hiding inside the shell while the pufferfish gains an additional layer of defense.
