Carcharhinus Leucas is a species of shark commonly known as the bull shark that inhabits warm coastal waters. However, there are several synonyms for the term that are used interchangeably among scientists and researchers. Some common synonyms are zambezi shark, Nicaragua shark, Van Rooyen's shark, and Ganges shark. The bull shark's aggressive nature and preference for shallow waters have earned it the nickname "the world's most dangerous shark." It is known for its ability to thrive in both salt and freshwater environments and has been found in rivers as far inland as 2,200 miles. Despite its fearsome reputation, the bull shark's importance in the ecosystem cannot be ignored.
