Seastars can live up to 35 years in the wild! It really depends on the species. Their wild habitat includes coral reefs, rocky coasts, sandy bottom, or even the deep sea of all the world’s oceans. There are approximately 1,800 different types of sea stars.

They have been known to live up to 10 years in aquariums.
