Whale sharks in Gulf of Mexico swim near the surface, take deep dives

Tracking whale sharks in the Gulf of Mexico revealed their use of near-surface waters, as expected, but also their use of deeper water off the continental shelf, including remaining at depth greater than 50 meters continuously for more than three days, according to a study published November 18, 2015 in the open-access journal PLOS ONE by John Tyminski from Mote Marine Laboratory, Florida, and colleagues from the US and Mexico.
