The finished result: How to Draw a Sea Turtle (Realistic, Step by Step)

By Show Me Step by StepPublished

Based on a video by Art for Kids Hub.

This sea turtle is drawn from above, the way you would see one gliding under a boat. A pointed oval shell, long front flippers, a ring of border plates and a honeycomb of plates in the middle. The team at Art for Kids Hub draws it with a black marker, then colors it with green, gold and two browns. They aimed this one at older kids, around 11 and up, but it is a good grown-up project too.

What you need

Plain white paper and a black marker for the outline. For color, a light green, a yellow-brown or gold, a medium brown and a dark brown. Markers work for the base colors. Colored pencils are better for the shading and spots because you can press light or hard. There is no pencil sketch step, so go slowly and keep your lines loose. A wobbly line looks more natural on a turtle anyway.

Sea turtle anatomy in plain words

  • Shell: an oval that is a little flat at the top, where the head comes out, and comes to a soft point at the tail end.
  • Front flippers: long, bent like an arm with an elbow, and much bigger than the back ones. That is how sea turtles swim.
  • Back flippers: short, rounded paddles that work like a rudder.
  • Plates (scutes): a ring of small border plates and larger plates down the middle and sides.

Make it look realistic, not cartoony

The line drawing on its own still looks like a cartoon. The color is what changes it. Shade each plate dark at the edge and lighter in the middle, so the shell looks domed. Put big spots near the edges of the flippers and small ones toward the middle. Then darken the skin right next to the shell and inside the wrinkles. Use the side of the pencil tip for soft shading. For more on that, see how to shade and how to draw with colored pencils.

Common mistakes

  • Flippers too short. Stubby front flippers make it a land turtle. Stretch them out past the sides of the shell.
  • Head too big. Keep it small, about a quarter of the shell's width.
  • Plates in neat rows. Real scutes are uneven. Let the shapes vary a little.
  • Shading everything the same. Leave the middle of each plate lighter, or the shell goes flat and muddy.

Drawing with grandkids

Draw side by side on two sheets, the way this video does, and take turns choosing the next step. Younger kids can stop after the marker outline and color it any way they like. Older kids can try the plate shading. Pause the video as often as you need. The coloring part goes fast. When you are done, cut the turtles out and glue them onto blue paper with a few wavy lines for water. That makes an easy ocean scene for the fridge.

Keep drawing ocean animals

Draw the Sea Turtle Shell as a Pointed Oval

1:22
Step 1: Draw the Sea Turtle Shell as a Pointed Oval - How to Draw a Sea Turtle (Realistic, Step by Step)

Start in the middle of the page. Draw a big curve for one side of the shell, then the other side. The shape is an oval with a soft, rounded point at the bottom. Close the top with a line that runs almost straight across, then curves back in. That flat part is where the head comes out. A slightly lopsided shell is fine. Turtles are not perfect ovals.

Tip

Leave room on both sides of the shell. The front flippers reach a long way out.

2

Add the Sea Turtle Neck and Head

1:58
Step 2: Add the Sea Turtle Neck and Head - How to Draw a Sea Turtle (Realistic, Step by Step)

Draw two short lines coming up out of the flat top of the shell. That is the neck. On top of them, draw an upside-down U with a small point at the very top for the head. Keep it small compared with the shell. A big head pushes the drawing toward cartoon, and this one is meant to look real.

Tip

If the head looks too round, make the point at the top a little sharper.

3

Draw the Long Front Flippers of the Sea Turtle

3:12
Step 3: Draw the Long Front Flippers of the Sea Turtle - How to Draw a Sea Turtle (Realistic, Step by Step)

From the upper right side of the shell, draw a diagonal line going out, then curve it down. At the tip, curve again, then draw a straight line back toward the shell to make an elbow. Curve in once more and join it to the shell. Repeat the same moves on the left so the two flippers mirror each other. Add a couple of short wrinkle lines where each flipper bends.

Tip

Turn your paper as you go. Curves are easier to draw when your hand moves toward you.

4

Draw the Sea Turtle Back Flippers and Tail

4:14
Step 4: Draw the Sea Turtle Back Flippers and Tail - How to Draw a Sea Turtle (Realistic, Step by Step)

At the bottom of the shell, draw a short S line coming out on each side. Then draw a second S line on the outside of each one to close it into a small paddle. These back flippers are much smaller than the front ones. Finish with a tiny pointed tail sticking out between them at the very bottom of the shell.

Tip

Keep the two back flippers angled out, like the turtle is steering.

5

Add the Eyes and the Inner Border of the Turtle Shell

4:52
Step 5: Add the Eyes and the Inner Border of the Turtle Shell - How to Draw a Sea Turtle (Realistic, Step by Step)

Put two small dot eyes near the top of the head. Then draw the border on the shell. Start with a straight line across the top, right under the neck. Follow the outside of the shell all the way around with a wobbly line, keeping a narrow gap between it and the edge. That gap becomes the ring of small border plates.

Tip

Keep the gap even all the way around. A ring that gets fat at one side looks off.

6

Divide the Sea Turtle Shell Border Into Segments

5:16
Step 6: Divide the Sea Turtle Shell Border Into Segments - How to Draw a Sea Turtle (Realistic, Step by Step)

Draw short lines across the border ring to split it into small sections. They look a bit like bricks laid in a circle. Space them roughly evenly and go all the way around the shell. These are the marginal plates of a real sea turtle, and they make the shell edge look thick and solid.

Tip

Do not measure. Slightly different widths look more natural than perfect spacing.

7

Draw the Plate Pattern in the Middle of the Turtle Shell

6:10
Step 7: Draw the Plate Pattern in the Middle of the Turtle Shell - How to Draw a Sea Turtle (Realistic, Step by Step)

Draw two short lines down the middle of the shell. Close each side with a sideways V to make a six-sided center plate. From each corner, draw lines out toward the border. Add shorter diagonal lines, then connect pairs of lines with curves to close more plates. Finish the bottom with a rainbow-shaped line and the plates around it. Now the shell has its honeycomb look.

Tip

Do the top half first, then the bottom. It is easier to keep the pattern balanced.

8

Color the Sea Turtle Body Green and the Shell Gold

7:18
Step 8: Color the Sea Turtle Body Green and the Shell Gold - How to Draw a Sea Turtle (Realistic, Step by Step)

Color the head, flippers and tail light green. Fill the shell plates and border with a yellow-brown or gold. Stay inside the black lines and keep the color even. This is the base layer, so it does not need to be perfect. The shading in the next steps will cover small gaps. Markers give strong color fast. Pencils give a softer texture.

Tip

Color in one direction on the shell so the texture looks tidy under the shading.

9

Shade Each Sea Turtle Shell Plate With Brown Pencil

7:46
Step 9: Shade Each Sea Turtle Shell Plate With Brown Pencil - How to Draw a Sea Turtle (Realistic, Step by Step)

Take a medium brown pencil. Go around the inside edge of each plate, pressing harder at the edge and lighter as you move toward the middle. Leave the center of each plate gold. Work plate by plate until the whole shell is done. The shell now looks domed instead of flat. A second pass with dark brown makes it richer.

Tip

Use the side of the pencil tip, not the point, for smooth shading without hard lines.

10

Add Brown Spots and Shading to the Sea Turtle Flippers

9:00
Step 10: Add Brown Spots and Shading to the Sea Turtle Flippers - How to Draw a Sea Turtle (Realistic, Step by Step)

With dark brown, add spots to the flippers and head. Make them big near the outside edges and smaller toward the middle so they blend. Then shade the skin right next to the shell and inside each wrinkle. Do the same around the neck and back flippers. That last bit of shadow is what makes your sea turtle look like it could swim off the page.

Tip

Press lightly first. You can always go darker, but colored pencil is hard to erase.
