10-12 years
Some animals that are still alive today and lived during the Cretaceous period include crocodiles, turtles, and some species of sharks. These creatures have remained largely unchanged in their basic form for millions of years.
Yes they do live in seas and oceans.Most of the sharks live in salty water itself ...because it body contains pores like substance it makes comfortable to live over there.....it lives from higher concentration to lower concentration this is nothing but diffusion through the skins of fish.......
