The Bay is noted for its aggressive bull shark population. The attacks were caused by the species bull shark and tiger shark. They include Ocean Motion, Fish Pipe, and Burt the Bull Shark. The bull shark can be up to in length at birth. Unfortunately, at the same time, a huge bull shark enters the river. In India, the bull shark may be confused with the Sundarbans or Ganges shark. The bull shark prefers coastal water, which is less than 100 feet in depth. In 1937 two commercial fishermen from Alton caught a bull shark in the Mississippi River.
