Step 8 - Add Lateral Line, Teeth, and Final Details
Next add a lateral line, teeth, and some final details. The lateral line swoops down gracefully from the top of the gill slits to the origin of the keel. Now give your shark some teeth. Add a 'hump' behind the eye and some muscle 'bulges' above and below the gill slits. Draw in the bases of the first dorsal and pectoral fins. Note that there is an L-shaped white patch at the rear edge of the pectoral fin. Lastly, indicate where the shark's backbone extends into the upper lobe of the caudal (tail) fin.
