Reptiles of the Ocean

Sea turtles are among the few, oldest reptiles in the ocean. They roam all regions of the earth, besides the polar regions. Some of the very first proto-turtles are believed to have existed over 220 million years ago, and it is no wonder they have survived so much with some turtles being able to live up to 100 years!

When closely observing a sea turtle, you will notice that they have very distinctive natural patterns and textures that run across the whole body, which makes them great subjects in art.

Step-by-Step Instructions on Creating a Realistic Sea Turtle Drawing

This tutorial will help guide you toward creating a realistic sea turtle drawing. Whether you are a beginner or professional, these easy steps will show you how to observe your sea turtle just through simple shapes and forms.

We will also closely study the scales, wrinkles, and shell, focusing on capturing these natural patterns and textures through drawing techniques.


Step 1: Prepare Your Materials and Observe Your Sea Turtle

It is important to have all your materials ready before you begin observing the sea turtle closely. This could be either from life or using a reference image to help you capture the way the animal glides through the water.

If you have the chance to visit an aquarium, it is encouraged to do so, otherwise, find an image of a sea turtle that you think will work well as a drawing.

Step 2: Find the Center of the Page and Draw a Point or Dot

Find the center of your page using a ruler and draw a point in the middle of the paper with a pencil. This is the point from which you will plan the basic foundations of your sea turtle sketch.

Step 3: Draw an Accurate Shape of the Shell with a Pencil

Using a pencil, draw an accurate shape of the sea turtle’s shell. This outline of the shell should be egg-shaped and tilted slightly on its side, with the left side being slightly wider than the right.

Step 4: Draw an Accurate Shape of the Head and Its Four Flippers

To start, sketch the general shape of the head first as an oval which is slightly smaller on the right side. The frontal flippers (the two flippers in the front) should be triangular-shaped. These lines can be sketched as straight lines initially.

The back two flippers can now be sketched in as more oval or circular-shaped, and they are also slightly hidden behind the shell.

Step 5: Outline Your Planning with a Darker Pencil

Begin outlining your initial planning for your sea turtle sketch with a darker pencil. Return to your reference image of the turtle and notice the details of its characteristics and features. Observe that the head has grooves and a beak.

The shell also has grooves and mounds. The flippers are paddle-shaped and rounded at the tips.

Step 6: Add a Lateral Line in the Middle to Define the Shape of the Shell

Add a lateral line that runs from the neck to the third flipper to the right. This will feature as the bottom base of the sea turtle’s shell casing. This is also where the sea turtle’s body will show below the shell.

Step 7: Sketch the Details of the Sea Turtle’s Flippers and Facial Features

First, sketch the details of the sea turtle’s facial features. This should include a line depicting the mouth, which curves downwards on the right, two small oval nostrils, and its eye (if only one is visible). You can add more dimension around the eye by adding extra lines above and below the eye.

The neck is shaped like a cylinder and fades or disappears below the shell casing.

Step 8: Begin Outlining Your Planning with a Pen

Using a pen or fine liner, begin outlining your pencil planning. Start with the head first and work your way around the sea turtle pencil sketch, filling all lines and initial details of the facial features.

Step 9: Erase All Pencil Lines and Planning

Once your ink has dried, erase all of your pencil lines and any initial planning by working from left to right. Once all lines are erased, you will begin to notice that the sea turtle illustration will start to take defining shape.

Step 10: Add More Details to the Facial Features with a Pencil

Begin adding more details to your sea turtle drawing with a pencil. Study the beak first and how it protrudes slightly above the lower lip. The nostrils are hollow. The scales and wrinkles wrap around the curvature of the head and neck, which are made up of triangles, hexagons, pentagons, and squares.

Attempt to create this pattern with a few loose scales scattered around the face, then blend them towards the wrinkles of the sea turtle’s neck.

Step 11: Fill the Eye and Leave a White Space for a Highlight

Fill in the details of the sea turtle’s eye. The eye should be filled but contain a small white highlight which will depict a slight glisten and shine. This will also give it more dimension and show the animal’s true character.

Step 12: Add Shading and Texture to the Body below the Shell Casing

Using a darker pencil, begin working on the tonal values for your sea turtle illustration by adding shading to the body below the shell. Focus on capturing the lines and shadows created in the creases and wrinkles of the turtle’s body.

Step 13: Sketch the Patterns Formed on the Frontal Flipper

Sketch the patterns and lines formed on the frontal flipper first. These scales are more oval- and rectangular-shaped. They should wrap up the side and over the top of the flipper.

Step 14: Sketch the Pattern Formed on the Shell

Next, focus on the pattern on the shell of your sea turtle. These large mounds and scales are called shutes. The shutes fit together like a puzzle and are made up of hexagons and pentagons. Be sure to leave space between your shutes if possible, to show the groove lines that run across the shell and in between the shutes.

The shutes that run along the lateral line on the shell should be placed next to one another and run along the side of the shell towards the tail.

Step 15: Add Shading and Texture to the Shell and Flippers

Continue by adding shading and texture to your shell and flippers with a pencil. Focus on defining the darkest parts of your sea turtle drawing and fill in any missing patterns, shapes, and details to your sea turtle sketch.

Step 16: Fill Your Shadow Areas Using Liquid Ink, Drawing Ink, or a Pen

Now that you have identified the darkest areas in your sea turtle sketch, begin filling these shadow areas using liquid ink, drawing ink, or a pen. Work from left to right if you are right-handed to avoid smudging and vice versa if you are left-handed.

Step 17: Finalize Your Drawing by Adding the Last Details with a Pen

Start to finalize your sea turtle illustration by adding the finer details with a pen or fine liner. You can work from your shadow areas outwards by softly fading and blending your tones and textures towards highlight areas of your sea turtle.

You can use stippling or cross-hatching techniques to define your values.

Step 18: Allow to Dry

Allow your sea turtle drawing to dry properly for at least one to two hours. This will keep your ink from smudging and fading. You can also add color if you want to make your sea turtle drawing more vibrant and realistic.

 Once it is completely dry, erase any existing pencil lines and sign your sea turtle illustration.
