Step 10: Use the lines and shapes on the top, right side as guides to draw the crab's other claw the same way. Follow the path of the short line and draw a thick, curved shape around it for the bottom section of the claw. Darken the U-shaped guide for the base of the claw. Don't darken the top line. At the top, lightly sketch the first part of the claw as a thin, curved, spike-like shape. Make the bottom thick and the top part thin. When you get the shape right, darken the lines. Draw a thin, spike-like shape for the bottom of the edible crab's claw too. Make the inner line jagged for the serrated edge.
Step 11: Use the top-most lines on the sides of the body as guides to draw the first set of legs. Draw the thick shapes of the brown crab's legs along the edges of the initial guides. Draw a thick, short segment of the leg wherever the guideline bends for a total of three segments per leg. Make the top segment thick at the bottom and thin and pointy at the top. Use the angled line on the right side as a guide to draw the other leg the same way. Draw two thick, short segments at the bottom and one pointy segment at the top.
Step 12: Use the long lines under the first set of legs as guides to draw the second set the same way. Follow the path of the guide on the left and draw the segments where the line bends. These legs are a bit longer, so use four segments instead of three. Make the top segments pointy. Draw the segments along the line on the right to create the crab's other leg the same way. Sketch lightly at first so you can easily erase if you make a mistake. When you get the shapes right, darken the lines.
Step 13: Use the lines below the previous legs as guides to draw the next set of legs. Draw the small segments along the edge of the guide on the left. Use five segments this time. The pointy tips of these legs should point down. Draw the edible crab's leg on the right along the path of the guide too. The two sides don't have to be perfectly symmetrical, but make them as similar as you can.
Step 14: Use the last lines under the body as guides to draw the brown crab's last set of legs the same way. Draw the segments along the edges of the guides. Use four segments per leg and make the bottoms pointy. The lines bend a lot more than the previous ones, so curve the segments accordingly. The bottom segments should point inward. Add an extra line at the bottom of the crab's body for the shell underneath.
