Bull shark
The Bull shark has been considered to be the culprit in the infamous series of five shark attacks in New Jersey in 1916 which resulted in four deaths over a 12-day period. Three of these attacks happened in Matawan Creek, a shallow tidal river, only 40 feet (12 metres) across, 1.5 miles (2.4 km) from bay waters, and over 15 miles (24 km) from the open ocean; not a location where any other large shark species would likely be found. A 7.5 foot (2.25 metres) Great White was captured two days after the last attack, however, just 4 miles (6.4 km) from the mouth of Matawan Creek, and contained human remains in its stomach. A 9-foot (2.7 m) Bull shark was also captured a day later only 10 miles (16 km) from Matawan. This has been a topic of debate for many years, and there is evidence that points at both, the Bull shark and the Great White as the culprits.
