Q: How do Bull Sharks and Great White Sharks differ? A: 1) Bull Sharks have small eyes, Great White Sharks don't. 2) Bull Sharks have wide, blunt snouts, while Great Whites' snouts are more sharply angled (conical). 3) The upper lobe of a Bull Shark's tail is long and low, while Great Whites' tail lobes are vertical, and more equal in size. 4) Bull Sharks have a big 'second dorsal fin' behind their main dorsal fin, whereas Great Whites have very small second dorsal fins.
