Bull Sharks are commonly mistaken for the sandbar shark.
They are very robust-bodied, have a large head with relatively small eyes and an extremely short blunt, rounded snout.
The upper side is dark dull gray fading to a white underside.
They have similar shaped dorsal fins.
Bull Sharks do not have an interdorsal ridge (ridge of skin going down the back between the two dorsal fins).
Their upper teeth are broad, triangular, and heavily serrated. The lower teeth are narrower and serrated.
