Known for their long flat heads, Hammerhead Sharks fish by smell, taste, and by sensing tiny electrical charges produced by their prey. Their strange heads act as natural hydrofoils, stopping Hammerheads from pitching and rolling side to side. They swim by swinging their heads from side to side.
No one knows why They have developed their elongated heads. Having their eyes on either side of their heads gives the Hammerhead Sharks poor vision. However, the Hammerhead Sharks' heads do enhance their sense of smell and taste. Their head is in effect a big, flat nose, with grooves for scent detection running along the leading edge. These Sharks are plentiful, so their heads must not hinder their hunting abilities.
Hammerheads teach how to be different and to try new things. However, remember that was with Hammerhead Shark's poor vision, there is a price for being different.
