Step 10: Use the V-shaped line on the right as a guide to draw the anglerfish's open mouth. Simply darken the lines as you follow the path of the V. Add a few more lines around the mouth for extra detail.

Step 11: Draw the anglerfish's teeth that line the inside of the mouth. The teeth are basically long, thin triangle-like shapes. Don't overthink it. Just add the different-sized thin spikes all over the mouth.

Step 12: Add a few lines between the teeth for the far side of the jaw and inside of the anglerfish's mouth. Try not to overlap these lines with the teeth.

Step 13: Use the line on top of the head as a guide to draw the anglerfish's lure. Follow the basic path of the guide as you darken the lines and make the base thicker. Use the circle at the top as a guide to draw the tip. The actual lure is made up of a smaller circle.

Step 14: Use the lines inside the circle as guides to draw the pectoral fin. Draw the base of the fin as a short curved line. Then follow the guides to draw the rest of it. Make the left edge of the fin wavier to represent movement and add a few lines within the shape for detail.
