Bull sharks (Carcharhinus leucas) are coastal sharks that inhabit the subtropical and tropical seas all around the world. One of the most remarkable characteristics of its distribution is associated with the fact that they can penetrate into fresh water up to many 100 km upstream in rivers. Bull sharks are characterized by a robust and rounded head. They can reach sizes up to 3.4 m and their feeding habits cover a wide range of prey (from bony fishes to mammals). The particular shape of its head makes it of special interest in my research, as its form may be associated with high performance as a top predator. Therefore my research will be based on the calculation of the theoretical bite force for this species based on a 3-D model. Time permitting these values will be compared to those obtained by restrained bite force. Since bite force is a measure of performance, this research will be one of the first approaches to understand possible contributions to their success as top predators.
