In this step-by-step tutorial, you’ll learn how to draw a sperm whale by starting with simple guiding lines and gradually shaping the body, fins, and details to create a smooth, realistic ocean animal.

STEP 1: Mark the Picture’s Width and Height

Begin by marking the overall width and height of the drawing area. Draw a long curved line to show the sperm whale’s back and head direction.

Short tip:
Keep this line smooth and light—it sets the flow of the entire drawing.

STEP 2: Draw the Body and Tail Base

Sketch the main shape of the whale’s body around the guideline, then form the base of the tail where it narrows toward the back.

Short tip:
Sperm whales have long, blocky heads and tapered bodies—don’t make the body too short.

STEP 3: Add Guidelines for Fins and Mouth

Add light guidelines to show where the flukes, fins, and mouth will go. These help balance the whale’s proportions.

Short tip:
Use simple curves instead of sharp angles for a natural underwater look.

STEP 4: Draw the Fins, Flukes, and Eye

Draw the shapes of the side fin, tail flukes, and mouth, then add the eye near the front of the head.

Short tip:
Keep the eye small—sperm whales have subtle facial features.

STEP 5: Refine the Whale and Add Details

Refine the entire whale shape by smoothing lines and adding details like the mouth line and texture. Carefully draw the baleen area inside the mouth.

Short tip:
Refine slowly to avoid overworking the lines.

STEP 6: Outline and Finish the Drawing

Outline the sperm whale using thick and thin dark lines. Add water details if desired, then erase all remaining guidelines.

Short tip:
Varying line thickness makes the whale look more finished and dynamic.
