How to Draw an Octopus Step by Step
Step 1: Draw the Head Shape
Begin by drawing a large rounded oval or dome shape.
This will form the octopus’s head and mantle.
Keep the lines light so adjustments are easy.
Step 2: Add Facial Guidelines
Draw a light vertical line down the center of the head.
Add a horizontal guideline where the eyes will be placed.
These guidelines help maintain symmetry.
Step 3: Draw the Eyes
Sketch two large oval eyes on either side of the center line.
Leave enough space between them for a natural appearance.
Add small pupils inside each eye.
Step 4: Create the Mouth Area
Draw a small curved line beneath the eyes.
For a cartoon octopus, you can add a smiling expression.
Keep the mouth simple and subtle.
Step 5: Sketch the First Tentacles
From the bottom of the head, draw several long curved arms extending outward.
Allow the lines to flow naturally.
Avoid making every arm identical.
Step 6: Add the Remaining Tentacles
Continue drawing all eight arms.
Overlap some tentacles to create depth and movement.
Vary their direction and length for a realistic look.
Step 7: Refine the Tentacle Shapes
Give each arm thickness by drawing parallel lines along both sides.
Keep the tentacles wider near the body and narrower toward the tips.
Step 8: Add Suction Cups
Draw rows of small circles along the underside of the arms.
These suction cups are one of the octopus’s most recognizable features.
Make the cups smaller near the tentacle tips.
Step 9: Refine the Body Outline
Review the overall shape of the head and arms.
Smooth out any rough lines and improve proportions.
Erase unnecessary construction marks.
Step 10: Add Texture Details
Lightly sketch subtle bumps and wrinkles on the skin.
Real octopuses often have textured surfaces that add realism.
Step 11: Ink the Drawing
Trace the final lines with a fine-tip pen or darker pencil.
Allow the ink to dry completely before erasing pencil marks.
Step 12: Add Base Colors
Color your octopus using shades such as:
- Orange
- Red
- Purple
- Pink
- Brown
You can also use creative fantasy colors if desired.
Step 13: Add Shading
Darken areas beneath the head and between overlapping tentacles.
Use smooth gradients to create a three-dimensional appearance.
Step 14: Add Highlights
Leave lighter areas where light naturally hits the body.
Highlights help make the octopus appear shiny and realistic.
Step 15: Finish the Artwork
Review your drawing and strengthen important details.
Add an underwater background if desired.
Your octopus drawing is now complete.
