Connecticut doesn’t have too many shark species, just four of them frequenting the coastline regularly, none of which are dangerous. The bull shark is one of the rare residents of CT infamous for its unprovoked and provoked attacks on humans.
Great whites generally do not make the Connecticut waters their home. Yet, they might have been spotted there because of their migratory pattern, as evident from recent sightings. In 2019, OCEARCH tagged Cabot weighing 533 pounds with a height of around 10 feet along the Long Island Sound area.
