How long can a starfish survive out of water?

Starfish can survive out of water for 5 days. Then, they die of dehydration. The only way a starfish gets on land is either by humans, or by the ocean itself. Starfish do manage to get back in the ocean, once the tide comes in. Sadly, many starfish don't make it, due to humans taking the little creatures home. Hope this helps! ............................................................If you dont want the starfish to die think of taking a bowl and scoop salt water out of the ocean into the bowl and put the starfish in it so it wont die.
