According to the International Shark Attack File, the Galapagos shark has been responsible for one fatal attack on a swimmer in the Virgin Islands. In locations where this shark is common, they often are attracted to divers, sometimes even becoming an obstacle. When divers take aggressive actions, these sharks are not discouraged, but instead become more excited. The Galapagos shark has been reported to display threat behaviors including arching of the back, raising the head, and lowering the caudal and pectoral fins while swimming in a twisted, rolling motion.
