You’ve seen it. If you’ve watched a single frame of Aquaman or even just scrolled past a shirtless photo of the guy on Instagram, you know the one. That massive, geometric half-sleeve of black triangles on his left forearm. It’s iconic. It’s rugged. And honestly? Most people think it’s just some cool movie makeup designed to make him look more like a DC superhero.
It isn't.
That jason momoa arm tattoo is as real as it gets. In a world where actors spend hours in makeup chairs having temporary ink airbrushed onto their skin for "character depth," Momoa’s most famous piece of body art predates his time as Arthur Curry by years. He actually had it back when he was playing Ronon Dex on Stargate Atlantis. If you go back and watch early episodes of that show, you can see them trying to hide it under bandages before they finally just gave up and wrote it into the character's backstory.
The Family God on His Sleeve
So, what is it? It’s not just a pattern. In Hawaiian culture, those triangles represent shark teeth. But it goes deeper than just looking "fierce." This specific design is a tribute to his family's 'aumakua.
In Hawaiian mythology, an 'aumakua is an ancestral guardian or family god. It’s basically a spirit that has passed on and returned in a different form to protect the living members of the family. For the Momoa clan, that guardian is the shark—or mano.
When you look at the tattoo, you're seeing nine rows of black triangles. They are inverted, creating a zigzag effect with the negative space. It's supposed to act as a spiritual shield. Momoa has explained in interviews that the ink is designed to "take the darkness out of your heart and bring the light in." He’s also joked—or maybe he was half-serious—that it's a practical safety measure. The idea is that if he’s ever out in the open ocean and a shark approaches, it'll see the tattoo, recognize him as one of its own, and keep moving.

It’s a cool thought. Probably don't test it yourself, though.
Why the Left Arm?
The placement isn't random. In many Polynesian tattooing traditions, the left side of the body is associated with the heart and the spiritual self. By placing the shark teeth on his left forearm, he’s literally wearing his protector on his sleeve.
It’s also interesting how this "real-life" tattoo dictated the entire look of the DCEU’s Aquaman. When Zack Snyder was first reimagining the character, he didn't want the clean-cut, orange-spandex-wearing guy from the old comics. He wanted something that felt ancient and powerful. He saw Momoa’s actual ink and decided to build the entire character's aesthetic around it.
If you look at the full-body "tattoos" Aquaman wears in the films, they are essentially an expansion of Jason’s real forearm piece. The movie version includes spearheads and more shark teeth that cover his chest and shoulders, all designed to blend seamlessly with the jason momoa arm tattoo he already had. It turned a piece of personal heritage into a global pop-culture phenomenon.
It’s Not the Only Ink He’s Got
While the forearm sleeve is the heavy hitter, Momoa is kind of a collector. He has several other pieces that people often miss because they aren't as visually aggressive.

- The Kids' Signatures: Just above his heart on his chest, he has the names of his children, Lola and Wolf, tattooed in red. These aren't just in a standard font; they are actual tracings of their signatures from when they were little.
- "Etre toujours ivre": This one is on his right forearm. It’s French for "to be always drunk." He got this one along with his step-daughter Zoë Kravitz and his ex-wife Lisa Bonet. It’s a reference to a poem by Charles Baudelaire about living life with passion—not necessarily a literal suggestion to stay buzzed 24/7.
- Pride of Gypsies: This is on his inner right forearm. It’s the name of his production company. It’s more of a professional badge of honor than a spiritual one.
- The Middle Finger: He has "Diablo" tattooed on his middle finger. It’s a tribute to a friend who passed away. He’s famously fond of showing it to the paparazzi when they get too close.
The Evolution into Traditional Methods
Momoa’s relationship with ink has actually changed over time. Recently, he’s moved toward more traditional, hand-tapped methods. In late 2022, he sat for a session with Sulu'ape Keone Nunes, a master of traditional Hawaiian tattooing.
This wasn't done with a modern buzzing needle. It was done with "moli"—traditional tools made of bone or wood that are tapped into the skin. This wasn't for a movie role either. It was a deeply personal ceremony to mark his head with a design that honors his ancestors. It shows that for him, the jason momoa arm tattoo wasn't just a phase of his youth; it was the start of a lifelong commitment to his roots.
Common Misconceptions
People get a lot of stuff wrong about his tattoos. One of the biggest myths is that the arm tattoo is a "sleeve of arrows." While they look a bit like arrowheads, the triangular shape is strictly meant to be shark teeth. Arrows in Polynesian tattooing often point outward to represent a warrior's path, but the "mano" teeth are specifically about the 'aumakua.
Another one? That he got the tattoo for Aquaman. As mentioned earlier, he’s had that piece for nearly two decades. He didn't change for the role; the role was changed to fit him.
What This Means for You
If you're thinking about getting something similar, there’s a right way and a wrong way to do it. Copying a celebrity’s tattoo note-for-note is usually a bad move, especially when it carries deep cultural or familial significance like this one. In the world of Polynesian "tatau," the designs are often specific to the individual's lineage and life story.

If you want to honor the aesthetic without "stealing" a family's crest, here are some things to consider:
- Research the Symbols: If you like the look of the shark teeth (the niho mano), understand that they represent strength and protection. Use them as a component, not the whole design.
- Talk to a Specialist: Don't just walk into a street shop with a photo of Jason Momoa's arm. Find an artist who specializes in Polynesian or Hawaiian designs. They can help you create a pattern that is unique to your own life.
- Respect the Tapu: Some designs are considered "tapu" (sacred) and shouldn't be worn by those outside the culture. A knowledgeable artist will steer you away from those.
The jason momoa arm tattoo is more than just a piece of cool celebrity trivia. it's a bridge between ancient Hawaiian traditions and modern Hollywood. It’s a reminder that even when you’re a global movie star, you can still carry your ancestors with you—literally.
Next time you see him on screen, look at the negative space between those triangles. It’s not just black ink. It’s a story about a guy who knows exactly where he came from, no matter how famous he gets.
Actionable Insight: If you’re planning a tattoo with cultural roots, spend at least three months researching the specific meanings of the symbols before booking your artist. Authentic Polynesian designs are "read" like a map, and you want your map to tell your own story, not someone else's.
