An octopus hiding in a shell

Two men on a beach found a shell that seems full, one of two friends took the initiative to open it. When the man finally managed to open the shell, a small octopus comes out, obviously very upset at having been dislodged. The octopuses use shells or coconut as a protective shell, a particularly useful tool when stopping in an exposed area or when it rests on the seabed. An elaborate system of protection.
