Bull sharks have a very sturdy body, and have a blunt, rounded snout, giving the Bull shark its name. The first dorsal fin is large and widely triangular with a pointed tip. The second dorsal fin is noticeably smaller. The pectoral fins are also large, and have sharp tips. Bull sharks have quite small eyes as compared to other carcharhinid sharks, which might mean that vision is not a very important hunting tool for this species which is usually found in muddy waters. Bull sharks are usually pale to dark grey above, and their undersides are white. In young Bull sharks, the fins have black tips which turn to a dusky colour as they grow.
