Sea Cucumber

When surprised by a predator, some sea cucumbers can expel their internal organs along with a sticky substance. They then can regrow their innards. Other sea cucumbers can expel all the water in their bodies, becoming hard and small. How would a sea cucumber know to get rid of its insides to escape a predator? This information was programmed into its DNA by its Creator.
