Danger to Humans
The Caribbean reef shark infrequently attacks humans. In general, a shark attack on a human is behaviorally similar to an attack upon natural prey. A human is more susceptible to being attacked if the shark is cornered and feels that there is no escape route. In situations like these, the shark may rake the victim during the attack resulting in lacerations.
Although these characteristics have not been recorded in specific association with the Caribbean reef shark, based on observations of gray reef sharks (C. amblyrhynchos), it is possible that C. perezi may display similar behavior. Possible signals indicating a Caribbean reef shark may attack (display threat):
