Step 10: Draw a similar shape, only this time a lot shorter under the sword for the bottom part of the swordfish's mouth.

Step 11: Use the triangle-like shape on top of the body as a guide to draw the dorsal fin. Follow the basic path of the guide but curve the shape more as you darken the lines. Swordfish and sailfish are very similar. To draw a sailfish, simply make the dorsal fin bigger by stretching the shape back toward the tail.

Step 12: Use the triangle-like shape on the bottom as a guide to draw the swordfish's pectoral fin on this side. Make it curve a bit more.

Step 13: Use the shape on the left as a guide to draw the anal fin. Make this fin curvier, too. Draw a couple of smaller fins near the tail and the dorsal fin on the other side of the swordfish's body.

Step 14: Draw the tail or caudal fin on the left side using the big triangle as a guide. Follow the basic path of the shape for the top and bottom edge of the fin. The line for the left side of the fin should come in more to the right toward the swordfish's body to form a sort of wide greater-than sign (>).
