Humans are not a shark’s natural prey. Shark attacks are usually a case of mistaken identity. But surfers beware. Those black, full-bodied wet suits make them look like seals to a shark on the hunt. (And they’re always on the hunt.)
Seals, sea otters, sea lions are their natural prey. Female humans in wet suits not only look like prey, they sometimes give off blood. If the sharks are hungry enough they will also eat each other.
