In 2015, the International Shark Attack File reported 164 shark-related incidents, but notably, there were zero reported attacks against scuba divers. Most attacks were classified as unprovoked, with the majority occurring in North American waters. As human populations grow and interest in water activities increases, shark-human interactions may also rise, though this year’s data shows no significant increase. It’s important to note that the total numbers can fluctuate each year due to various environmental and social factors.
