The term “shell” in literature is imbued with layers of meaning, ranging from the physical to the metaphorical. In some works, it denotes a literal protective covering, as seen with the turtle of the edible green turtle in [1] or the opercular valves described in [2] and the delicate egg-shell in [3]. Beyond its concrete sense, “shell” also becomes an emblem of brevity or confinement—the phrase “in a nut-shell” encapsulates an entire legal science in [4] and [5], while it symbolizes a barrier or a protective retreat, as hinted at when one character retreats into her own shell in [6] or is reduced to something fragile, like an egg-shell, under duress in [7]. The word’s versatility extends further to capture moments of explosive force or decisive action, such as the impact of a bomb-shell in [8] or the act of dislodging one’s shell as a metaphor for personal transformation in [9].
