Some fish do have a secondary heart located close to the tail end of their body. This is because fish have a single circulatory system which is inefficient in maintaining a high blood pressure from the heart to the gills to the body and back to the heart (unlike us who have a double circulatory system - blood is pumped to lungs, then back to heart and then to body before returning to the heart to repeat the process).
Two fish that travel very long distances in the sea are the tuna and the salmon. Tuna migrate across oceans in search of food and to reproduce, while certain species of salmon can travel thousands of miles from the ocean to their freshwater spawning grounds.
It was speculated that some dinosaurs may have had two hearts to help pump their blood around. Earth worms supposedly have six hearts.
No, not all animals with two-chambered hearts live in the water. For example, some amphibians, like frogs, have two-chambered hearts and live both on land and in water.
