Great white shark [SEP] Shark bite incidents
Many of the incidents seemed to be "test-bites". Great white sharks also test-bite buoys, flotsam, and other unfamiliar objects, and they might grab a human or a surfboard to identify what it is. Contrary to popular belief, great white sharks do not mistake humans for seals. Many bite incidents occur in waters with low visibility or other situations which impair the shark's senses. The species appears to not like the taste of humans, or at least finds the taste unfamiliar. Further research shows that they can tell in one bite whether or not the object is worth predating upon. Humans, for the most part, are too bony for their liking.
