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 lack an actual brain and instead use a complex nervous system to sense the environment. Nerves run from its mouth down each arm to eyespots at the ends of those arms. This allows starfish to distinguish between light and dark.Full Answer >
Starfish move using tube feet on their undersides. Their feet use seawater to form a hydraulic system. The starfish's vascular system is open and relies on the water around it rather than internal pressure. Starfish can only move outside of water for a short time. A starfish left out of water for too long loses its ability to move, and it dies if not quickly returned to the ocean.Full Answer >
