This stocky, powerful shark is named for its pale yellow-brown to grey skin, which lacks any distinctive markings. This provides perfect camouflage when swimming over the sandy seafloor in its coastal habitat (3). It has a flattened head with a short, broad snout, and the second dorsal fin is almost as large as the first (2). The lemon shark's retina has a specialized horizontal band across the middle, which is disproportionately rich in cones that discern fine detail and colour in well-illuminated conditions. This 'visual streak' is thought to provide the shark with a particularly clear view of its underwater world (4). This shark is potentially dangerous to humans due to its large size and powerful bite, and though there have been some unprovoked attacks, many were the result of provocation from divers and swimmers (2) (3).
