Step 6: Draw a bigger triangle-like shape on the right side of the hammerhead shark's body for the tail or caudal fin. First draw a long, diagonal line on the right side, then connect that line to the body using two smaller diagonal lines.

That's it for the initial sketch! From this point on, press harder with your pencil to get a more defined sketch.

Step 7: Draw a circle on the right edge of the rectangle for the hammerhead shark's eye. Shade the inside of the eye except for a tiny circle to represent glare. Draw a few lines around the eye for extra detail. The other eye isn't visible because of the perspective.

Step 8: Use the rectangle as a guide to draw the hammerhead shark's head. Draw the top part of the shark's head first by lightly drawing a curved line as you follow the path of the rectangle. Darken the top part of the head when you get the curved structure right. Now draw the rest of the head. Follow the path of the guides as you lightly sketch the head. When you get the structure right, darken the lines.

Step 9: Draw the hammerhead shark's open mouth under the initial rectangle shape. The mouth consists of a wide, curved line on top of a straight line.
