Sharks are a very incredible animals.Sharks hunt down there pray by swimming rapidly behind them.Like other sharks, the skin of a Great White is very tough and studded with tiny, tooth-like scales called “dermal denticles”. Dermal denticles protect the skin from damage and are replaced continually. Each individual denticle has a flat, table-like crown that has a series of raised ridges. These ridges reduce the drag and noise generated by a shark’s swimming movements, enabling the Great White to glide efficiently in ghost-like silence.The eyes of a Great White are relatively large and well developed. The retina (light-sensitive tissue lining the back of the eyeball) of this species contains both rods and cones in a similar ratio to that of humans (about 4 to 1). This suggests that the Great White is highly visual and has acute color vision. Although different parts of its retina are adapted for bright and dim light conditions, it is believed that the Great White is primarily a daytime hunter.The sharks are very intelligent just like squids
