for example, “Sandbar Sharks move between the northeastern United States and the Yucatan Peninsula of Mexico, a distance of about 5,600 km (3,480 miles) (Helfman)”. Sharks will either cross oceans for migration or they will stick to the coast, but either way they can travel thousands of miles for migration. Vertical migrators do not travel great distances along coasts or across oceans like horizontal migrators, but more impressively, these migrators are experiencing a drastic change in temperatures and pressure. Vertical migrators dive down and resurface over hundreds of meters within a short amount of time, for example, “White Sharks may move up and down between the surface and 200-m (660-ft) depths as often as 96 times in 24 hours (Helfman).”…
