If by creatures, we mean animals, they require oxygen to survive. Humans get oxygen from the air by using their lungs. Underwater animals can get oxygen directly from the water (water contains dissolved oxygen) by using their gills. Other animals don't have gills (like dolphins) so they live underwater but come up to the air every now and then to get their oxygen.
Life in general is very good at living in water. For billions of years, creatures were ONLY able to live in water. Land animals, like us humans, evolved later to live on land so now we are so poorly adapted for life underwater that it would kill us.
