This issue also implies that all shells can do this, as King Triton stated, "The sound of the sea is captured in every single shell." In the original book, the mermaid has her tongue cut off in exchange for legs. In the movie, this was changed to having her voice represented by a glowing orb, most likely to make the scene less violent but still just as intense for the audience.

When he learns of his daughter's plans to run away with the aid of Hook, he enchants a seashell so that she will have no reason to leave as it will remove her singing voice. He gives it to Hook in trade for magic squid ink which will help him defeat the Dark One. Hook tells Ursula of her father's plan, and she, in turn, gives Hook the magic squid ink. When Poseidon finds out that Ursula knows, he takes Hook's squid ink away who then retaliates by using the shell to take Ursula's singing voice.
