How can you tell if an abalone is alive?

To determine if an abalone is alive, gently touch its shell; a responsive abalone will retract its foot and close its shell when stimulated. Additionally, you can check for movement or signs of breathing, as live abalones will often move slightly or have visible gill movement. If the shell remains open and there is no reaction, the abalone is likely dead. Always ensure you handle them carefully to avoid harming them.
