Full Answer

  1. Soak the starfish

    Soak the starfish in rubbing alcohol for 48 hours, or place the starfish in a solution made with 1 part bleach and 3 parts water for one minute. Remove the starfish with a slotted spoon, and place it on several paper towels.

  2. Place the starfish in a sunny location outdoors

    Weigh the arms of the starfish down with a heavy object, such as rocks, to prevent them from curling. To speed up the drying process, place the starfish on top of a mixture of equal parts baking soda and salt in a shallow dish, and allow the starfish to dry in a sunny location outdoors for 48 hours.

  3. Apply a protective sealant

    If desired, apply a sealant, such as an aerosol polyurethane, to complete the preservation.

    How can you tell if a starfish is dead?

    A:

    The key to determining if a starfish is alive or dead is to look for movement. However, because starfish are not the most mobile organisms on the planet, it can be difficult to tell if they are alive or dead. If you cannot observe any movement at all, the starfish is probably dead.

  • Q:

    How does a starfish eat?

    A:

    Most starfish, also known as sea stars, eat by prying open the shells of prey such as clams or oysters with their arms, pushing their stomachs out their mouths and into the prey's shell, partially digesting the animal and then pulling their stomachs back into their mouths. Starfish that don't have suction disks swallow prey whole and afterwards eject undigested parts.
