PALM BEACH, Fla. (CIRCA via STORYFUL) — A school of blacktip sharks was caught swimming off Palm Beach, Florida, in aerial footage shared to Facebook last week.
The video of the sharks was shared by Elasmobranch Research Laboratory, which wrote that the footage allowed scientists to study the motion of the sharks, "such as tail beat frequency, to better understand their locomotion."
