New Hampshire doesn’t have a long coastline, extending to not more than 18 miles, which is why the surrounding waters aren’t home to many sharks. Of the ones found along the NH coast, some, like the basking sharks, are big, reaching heights over 30 feet. The spiny dogfish is in the list of smaller sharks with a height of 4 feet. Lake Winnipesaukee, New Hampshire’s largest water body, has several; shark species like the sandbar shark, tiger shark, and basking shark.
