Q:

How can you preserve starfish?

A:

Quick Answer

To preserve a starfish, soak it in rubbing alcohol for up to 48 hours before placing it outdoors to dry. The drying process can take several days, but it may be hastened by placing the starfish on a bed of salt and baking soda. Choose a large container to ensure there is enough space for heavy objects to weigh the arms down. Add a sealant to the starfish after drying, if desired.

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.

    How do starfish mate?

    A:

    Starfish can reproduce either sexually or asexually. Both male and female starfish exist, though they are externally indistinguishable from each other. They breed by releasing eggs and sperm into the water. The sperm fertilizes the eggs, and the resultant larvae eventually settle on the ocean floor to grow.

  • Q:

    Do starfish have bones?

    A:

    Starfish do not have bones, but instead have a series of hard plates that provide structure and support to their bodies. Starfish and other critters like them are called echinoderms, or marine invertebrates, which are tailed, finned animals that have backbones — they are not actually fish at all.
