The sharks have been genetically altered specifically to increase their intelligence as part of the research project's goal to use shark brains to stimulate human brain growth. This genetic modification is the central catalyst for the film's events, the enhanced intelligence allows the sharks to communicate, plan coordinated attacks, and outsmart the humans, transforming them from experimental subjects into apex predators again.
