How to Preserve a Starfish
Starfish are not actually fish, but rather marine creatures related to sand dollars and sea urchins. There are more than 2,000 species of starfish in our oceans, in numerous colors and with varying numbers of arms, so finding a deceased one washed up on the beach is not uncommon. Many people enjoy bringing these unique sea creatures home as souvenirs, but they must be properly preserved before being displayed. Preserving the starfish will help keep them free of odor and in good condition.
Things You'll Need

1
Clean the starfish. Wash it with warm water and a small amount of mild soap.
-
2
Soak the creature in rubbing alcohol for approximately 48 hours. You do not need to clean the starfish first, though you may do so if you choose. If you prefer not to use rubbing alcohol, you can substitute formalin, a solution of 1 part formaldehyde and 5 parts water. Using this solution will give the starfish a strong chemical odor that will gradually lessen once it has dried completely.

3
Dry the starfish completely, preferably in sunlight. Lay it on a flat surface and weigh down each arm with a stone so the arms do not curl during the drying process. Once it is thoroughly dry, display the starfish in a dry area of your home.

Tips & Warnings
Always be sure the starfish you are preserving is deceased. Living starfish feel firm, while dead ones feel limp. In addition, the tube-like feet on the underside of the living creature will respond to touch if it is alive.
If you find a living starfish on the beach, put it back in the water.
To whiten a starfish after the preserving process is complete, soak it in a weak solution of bleach and water for a few minutes.
Be careful when selecting a display area for your preserved starfish. The creatures are delicate and can be damaged easily.
