Social Sharks: "First" Video Evidence
Feb. 27, 2014—Some shark species have long been known to school (or form groups) with their own kind, but now, for the first time, researchers near Hawaii have documented schooling of several different shark species. The researchers affixed small cameras to shark fins to see this behavior without any human presence.
Editor's Note: National Geographic's Crittercam pioneered camera placement on sharks, particulary with gray reef sharks in Palau and Johnson Atoll. Shark aggregation, or schooling, was documented by Crittercam, but not involving different species, as has been recorded in this video.
