What is a "bull shark"?

A bull shark is a formidable species of shark known for its aggressive nature and ability to adapt to both saltwater and freshwater environments. It is commonly found in coastal waters and rivers around the world. The bull shark gets its name from its stocky build and powerful, muscular appearance. It can grow to impressive sizes, with females typically being larger than males. One distinctive feature of the bull shark is its ability to tolerate low salinity levels, allowing it to venture far upriver into freshwater habitats. This adaptability makes the bull shark one of the few shark species capable of thriving in both marine and freshwater ecosystems. Bull sharks are opportunistic predators, feeding on a variety of prey including fish, turtles, birds, and even other sharks.
