Seabed and fish guides
Draw a light curved band across the bottom of the page for the seabed, then a light oval in the upper right for the fish body.
Seabed and fish outline
Trace the seabed line over the curved band with a few small rock bumps, then trace the fish body outline over the oval guide.
Tail and fish details
Attach a triangular tail fin to the back of the fish, then add an eye, a top dorsal fin, and a small bottom fin.
Fish stripes
Add three curved vertical stripes across the fish's body.
Branching coral
Draw a branching coral shape rising from the seabed with three forked branches.
Coral texture and seaweed
Add small bump texture dots along the coral branches, then three tall wavy seaweed ribbons rising from the seabed.
Small fish, bubbles, shells
Add two tiny fish near the seabed, a trail of rising bubbles above the fish, and two small shells resting on the seabed.
Ink the lines
Go over every kept line with dark ink, then erase the light seabed band and fish oval guides.
Color the scene
Fill the water pale blue, the fish orange with white stripes, the coral pink, and the seaweed green.

Tips for Better Underwater Drawings

Squint at your reference until it blurs into 3–4 big shapes — draw those shapes first. Every landscape that "looks off" skipped this step.
Detail only the focal area and let the edges stay loose. The viewer’s eye goes where the detail is; detail everywhere means focus nowhere.

Underwater Drawing FAQ

How do you draw underwater easily?

Start with a horizon line and two or three big simple shapes, keeping your lines light. Refine the outline, add the defining details, then erase the construction shapes. The nine-step method above breaks this down — most people get a recognizable underwater on their very first try with it.

How long should it take to draw underwater?

A simple underwater drawing takes about 15 minutes following this tutorial. A quick doodle version can be done in two or three minutes, while a detailed, fully-shaded study might take an hour. Speed comes with repetition — the second attempt is always faster than the first.

What do I need to draw underwater?

Just a pencil, an eraser, and any paper. An HB pencil for construction lines and a 2B for final outlines is a nice upgrade, and colored pencils or markers finish it off — but nothing on this page requires special supplies.

Can kids draw underwater?

Yes — underwater is very manageable once you use construction shapes, and this method was written for first-timers. Kids can follow the same steps; just expect wobblier lines and more charm.
