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

Starfish take in oxygen and dispel carbon dioxide through their tube feet, thin skin and a hole located on top of their body, and circulate the gases throughout their body using a water-vascular system. Their respiratory system is rudimentary and sometimes nonexistent.Full Answer >
Starfish exhibit several unique adaptations that enable them to survive in the world’s oceans, including radially symmetrical bodies, unique tube feet that permit movement and the ability to regenerate lost arms. About 2,000 different starfish species inhabit the oceans, and while each has adapted to its unique surroundings, they all exhibit these three adaptations.Full Answer >
