How to Draw a Crab
In this simple drawing tutorial, you will learn how to draw a crab step by step. In this simple guide, we’ll break down how to draw a crab in just 9 easy steps—no need for a beach vacation to bring the sea to your sketchbook!
How to Draw a Crab – Fun, Easy, and Full of Claws!
Crabs are some of the most fascinating and funny creatures in the animal kingdom. With their sideways walk, powerful pincers, and armored shells, they make excellent drawing subjects—especially for beginner artists and kids. In this tutorial, you’ll learn how to draw a crab step by step, from basic shapes to a fully colored crustacean. Grab your sketchbook, and let’s get started on this claw-some art adventure!
Crabs: Nature’s Sideways-Walking Marvels
Before we start drawing, let’s take a closer look at the real stars of this lesson: crabs!
Crabs are decapod crustaceans, which means they have ten limbs—eight walking legs and two claws (also called chelae). Scientists have identified over 4,500 different species of crabs worldwide, ranging from tiny pea crabs that are smaller than a fingernail to giant Japanese spider crabs with leg spans of up to 12 feet!
You can find crabs in oceans, freshwater rivers, mangroves, and even on land. Some of the most common types include:
- Blue crabs (found in the Atlantic and Gulf Coasts of the U.S.)
- Fiddler crabs (with one claw much larger than the other!)
- Hermit crabs (which live in borrowed shells)
- Coconut crabs (giant land crabs that can crack coconuts!)
Crabs use their claws for communication, defense, and food gathering, and their hard exoskeleton protects them from predators. They’re quirky, efficient, and surprisingly complex—just like good art!
Why Drawing a Crab Is a Great Idea
Crabs are not just scientifically cool—they’re also a fun challenge for artists of all ages. Their symmetrical bodies, layered legs, and expressive claws help you practice structure, repetition, and character. Whether you’re drawing a realistic crab or a cartoon-style crustacean, you’re building valuable drawing skills as you go.
Plus, a crab drawing is perfect for summer-themed art, ocean projects, or just adding a splash of sea life to your sketchbook.
What You’ll Need to Draw a Crab
Before diving into the tutorial, make sure you have everything ready. The good news? You don’t need much to draw an awesome crab:
- A pencil (preferably with an eraser for easy corrections)
- Black pen or fine liner (for outlining your final sketch)
- Drawing paper or a sketchbook
- Colored pencils or markers (reds, browns, oranges, and maybe some ocean blues for background!)
- Optional: ruler (for straight guidelines) or a circle template (to help with the body shape)
Time needed: 15 minutes
How to Draw a Crab in 9 Steps
- Start with the Crab’s Main Body
Begin your drawing by sketching the crab’s body. Think of a wide oval or rounded trapezoid shape with a subtle notch at the bottom center—it’s slightly wider at the top and narrows toward the bottom. This is the crab’s main shell, or carapace.
- Add the Eyes and Side Shell Segments
Now, add two small eye stalks poking up from the top of the shell. Draw two short curved lines and small circles on top—these are the crab’s goofy, expressive eyes. On either side of the main body, add oval shapes to mark where the side shell segments or base of the claws will attach.
- Sketch the Claw Shapes
Next, draw the top sections of the crab’s claws. These should rise above and curve away from the body like large mitts. Make sure the claws are big and exaggerated—they’re a crab’s most iconic feature! Each claw should have a pincer shape, with the top part slightly longer and curving down.
- Complete the Claws
Finish the claws by drawing the lower segments, closing the pincer shapes. These should look like hooked teardrops that meet the upper part, forming a complete crab claw on each side. Now your crab looks like it’s ready to defend itself—or give you a tiny high five!
- Draw the Front Legs
Under the crab’s body, draw two curving legs on each side. These should bend outward and slightly upward like stretched-out arcs. They represent the crab’s front walking legs and add to the crab’s wide, grounded look.
- Add the Central Underside
In the center beneath the main body, draw a small horizontal oval shape. This part represents the crab’s underside or abdominal plate, which completes the shell’s structure. Also, you need to add short lines on the crab’s legs to create a realistic texture of the crab’s protective body layer.
- Draw the Swimming Legs
Time for more legs! Add another set of curved legs underneath the front pair on each side. These should curve downward a bit more sharply. Don’t forget—crabs usually have 8 legs (not counting claws), so you’re building up to that here. In this step, you draw the bases of the crab’s swimming legs.
- Finish the Legs
Complete the crab’s legs by drawing the final pair on each side, with slightly thicker tips—these legs can also serve as paddles for swimming. Add a few small detail lines across the leg joints and claws to give the limbs more shape and structure.
- Color Your Crab!
Now for the fun part—coloring! Use bold reds, oranges, or even deep browns to bring your crab to life. Most cartoon-style crabs are red, but feel free to get creative. You can also shade the undershell in a different tone for contrast. Once colored, your crab is ready to scuttle off into an ocean adventure!
You Did It – Your Crab Is Ready to Scuttle!
Congratulations! You’ve just learned how to draw a crab from scratch—shell, claws, and all. Whether you followed along as a beginner or drew with your kids, we hope this tutorial made the process simple and enjoyable. Don’t worry if it’s not perfect—every crab has its own quirky shape, and that’s part of the charm!
