Galeophobia is the medical term for a fear of sharks. The name galeophobia derives from the Greek language with galeos meaning shark and phobia meaning fear.[1] This phobia is diagnosed using DSM-5 criteria and is characterized by a patient showing marked fear or anxiety about sharks that leads to severe impairment of their quality of life.[2] Although it is not known exactly how many people have been diagnosed with galeophobia, a study conducted in 2015 revealed that just over half (51%) of Americans are absolutely terrified of sharks.[3]
