The ocean is a nightmare to draw. Honestly, it is. You sit down with a fresh sheet of paper, thinking you'll sketch a peaceful reef or a breaching whale, but ten minutes later, you've got a blue blob that looks more like a spilled slushie than the Pacific. The struggle is real. Most people focus on the wrong things in the ocean drawing, trying to capture every single wave or every scale on a fish, and they end up with a cluttered mess.
Water isn't a solid object. It's a lens. It bends light, shifts colors, and hides things in the shadows. If you want to get good at this, you have to stop drawing what you think the ocean looks like and start drawing what is actually there. It’s about the physics of light, not just the shade of blue you picked up at the craft store.
The Physics of Deep Water and Light
Most amateur sketches fail because they use the same brightness for everything. That’s not how the sea works. As you go deeper, the water absorbs colors. Red goes first. By the time you’re thirty feet down, everything is a muted green or blue. If you’re including things in the ocean drawing like a shipwreck or a shark at depth, and you use bright red paint, it’s going to look fake. It just will.
Professional marine artists like Wyland or the late Guy Harvey understand "selective absorption." They know that the further away an object is underwater, the more it blends into the background color of the water itself. This is called atmospheric perspective, but for the ocean. It’s "hydro-perspective," if you want to get technical.
Light also doesn't just hit the surface and stop. It creates "caustics." Those are the dancing, wiggly lines of light you see on the sandy bottom or on a turtle's back. If you miss those, your drawing stays flat. It stays boring. You need that movement.
Getting the Surface Right
The surface isn't just a jagged line. It’s a series of planes. Imagine a mirror that’s been smashed and then put back together on a vibrating table. That’s the surface of the sea.
When you’re looking up from underneath—which is a popular perspective for things in the ocean drawing—you see Snell’s Window. This is a phenomenon where you can only see the world above the water through a specific circle directly overhead. Outside that circle, the surface acts like a perfect mirror, reflecting the bottom back down at you. It’s a trip. Most people don’t include this, and that’s why their underwater scenes feel "off."
Why Anatomy Beats "Vibes" Every Time
Let’s talk about the animals. People love drawing dolphins. They’re iconic. But people usually draw them like long sausages with fins.
Dolphins have skeletal structures. They have a melon—that fatty area on their forehead for echolocation—that gives their head a specific shape. If you don't get the blowhole placement right, or if the dorsal fin is too far forward, the whole thing looks like a cartoon. If you want a realistic things in the ocean drawing, you need to study the silhouette.
- Sharks aren't smooth. They're covered in dermal denticles, which are basically tiny teeth. While you can't draw every "tooth" on the skin, you should reflect how they catch the light. They have a matte texture, not a glossy one.
- Jellyfish are 95% water. They shouldn't have hard edges. Use soft gradients.
- Coral isn't just a rock. It’s a colony of living organisms. Look at the branching patterns of Acropora versus the brain-like folds of Meandrinidae.
Details matter. A lot.
The Problem with Seaweed
Everyone draws seaweed like long, wavy ribbons of green. But "seaweed" is a massive category. You've got Bull Kelp (Nereocystis luetkeana), which has a huge gas-filled bulb at the top to keep it floating toward the light. Then you've got Sargassum, which looks like tiny golden grapes.

If you just draw generic green wavy lines, your things in the ocean drawing lacks character. It lacks a "sense of place." Are you drawing the cold waters of Monterey Bay? Then you need kelp forests. Are you drawing the Caribbean? You need sea fans and staghorn coral.
Composition and the "Hidden" Ocean
Composition is where most artists lose the plot. They put a shark in the middle, a treasure chest on the left, and a mermaid on the right. It’s too symmetrical. The ocean is chaotic. It’s vast.
To make your things in the ocean drawing feel "real," you should embrace the "negative space." Use the darkness of the deep sea to frame your subject. Maybe only half of the whale is visible, and the rest fades into the dark blue abyss. That creates mystery. It creates scale.
Texture and Medium
What are you using? Pencil? Watercolor? Digital?
- Watercolor is king for the ocean because the paint literally behaves like water. You can do "wet-on-wet" techniques to get those soft, blurry backgrounds that mimic the haze of the deep.
- Colored Pencils are harder. You have to layer. You can't just press hard with a blue pencil and call it a day. You have to layer greens, purples, and even oranges into the shadows to give the water depth.
- Digital Art allows for layers and "blend modes." If you’re working digitally, use an "Overlay" or "Color Dodge" layer to create those light rays (crepuscular rays) coming from the surface.
Common Mistakes Beginners Make
I see the same errors over and over. People draw bubbles as perfect circles. Bubbles aren't circles; they’re wobbling spheres that flatten as they rise. They also don't just go in a straight line. They swirl in the wake of whatever is moving.
Another big one: the "Blue Myth."
Water isn't always blue. Sometimes it’s grey. Sometimes it’s muddy brown or vibrant turquoise. The color of your things in the ocean drawing should depend on the weather you’re trying to depict. A stormy sea isn't blue; it’s a terrifying slate grey with white foam that looks like torn paper.
Scale and Perspective
If you draw a tiny fish next to a huge coral, it looks fine. But if you draw a tiny fish next to a huge whale, and they both have the same amount of detail, the scale is broken. The further away something is, the less detail it should have. This is basic stuff, but in the ocean, the "haze" of the water makes this effect much more dramatic than it is on land.
Actionable Steps for Your Next Drawing
Stop Googling "how to draw water." It won't help as much as you think. Instead, do this:
- Reference Real Photos: Go to NOAA's Photo Library and look at actual underwater photography. Notice how messy the "floor" of the ocean is. It’s covered in detritus, broken shells, and silt. It’s not a clean sandy beach.
- Master the Gradient: Practice drawing a box that goes from very light blue at the top to almost black at the bottom. If you can’t get a smooth transition, your ocean will always look choppy.
- Study Silhouettes: Try to draw ten different ocean animals using only black ink. If you can recognize the animal just by its shape, you’ve mastered its anatomy.
- Add Marine Snow: This is the secret ingredient. In the real ocean, there are tiny bits of organic matter floating everywhere. Artists call it "marine snow." Adding a few white flecks or tiny "dust" particles to your things in the ocean drawing immediately makes it feel like it’s underwater rather than in a vacuum.
- Focus on the Eye: If you are drawing a living creature, the eye is the focal point. Fish eyes are different from human eyes. They are often more spherical and have a different reflective quality. Get the eye right, and the viewer will forgive a lot of other mistakes.
The ocean is a foreign planet right here on Earth. Drawing it requires a shift in how you see the world. You aren't drawing "things"; you are drawing the way light struggles to survive in a liquid environment. Master the light, and the rest of your things in the ocean drawing will finally start to look like the masterpiece you’ve been picturing in your head.
Start with a single object. A single shell. A single rock. Build the environment around it. Don't rush. The sea has all the time in the world, and your art should too.
