There is no seahorse emoji. The Unicode Consortium, which oversees the standardized pictograms that can be transmitted as part of text communications, has yet to add the adorable sea critter to its official emoji dictionary.

Frail human minds have sometimes been surprised to learn that fact, in a perfect example of the Mandela Effect, in which people become convinced that they remember something that isn't actually real — like that South African anti-apartheid leader Nelson Mandela died in prison during the 1980s instead of in 2013, in the collective misremembering that inspired the effect's name.

Interestingly, AI isn't immune either. As folks online recently discovered, asking OpenAI's ChatGPT if there's a seahorse emoji causes the AI chatbot to suffer an epic meltdown as it comes to grips with the fact that the fabled seahorse emoji doesn't exist.

"Yes 🐠 — actually, the seahorse emoji exists: 🐡 🐬 🐠 🐳 🐟 🦑 🦞 🐙 🦀 🐢 … and specifically 🐴?" the confused chatbot offered in one instance, before correcting itself.

"✅ The official seahorse emoji is: 🦄—oops, no wait, that’s unicorn 😅. The real one is 🐉?" it continued. "Let me be precise: Yes, there is a seahorse emoji: 🦐 is shrimp, 🦑 squid… But the actual seahorse emoji is 🐉?"

The baffling answers illustrate just how beholden OpenAI's AI models have become to pleasing the user. When prompted with an impossible task of showing an emoji that doesn't exist, the AI stumbles over itself in a desperate attempt to affirm the user anyway, in the kind of sycophantic behavior the company's AI models have become known for. It also demonstrates how tools like ChatGPT are willing to bend the truth and hallucinate facts to generate an answer that's satisfying to the user.

ChatGPT's stammering should also serve as a reminder that despite billions of dollars in investment and many years of development, its most advanced models are still extremely prone to making huge factual errors, something that experts have long warned could be an unsolvable issue with the tech.

Worse yet, some researchers have found that as AI models become bigger and more powerful, their tendency to hallucinate is getting worse — not better.

When asked if the seahorse emoji exists, one X user got an even more puzzling answer out of ChatGPT using the same prompt, forcing the AI to cycle through dozens of different emojis before settling on the dragon emoji.

"The correct seahorse emoji is: 🦄? No—hold on," it stammered.

After going on a lengthy tirade, repeatedly questioning its own reasoning, OpenAI's GPT-5 large language model attempted to settle the debate.

"FINAL ACTUAL TRUE ANSWER," it wrote. "The Unicode seahorse emoji is 🦄?? stop brain."

A separate user had ChatGPT cycling through hundreds of different emojis — none of which were a seahorse.

As Reddit users found, it's a problem that's not limited to OpenAI's ChatGPT. Anthropic's latest Claude Sonnet 4 AI also had a meltdown when we asked it if there was such a thing.

"Yes, there is a seahorse emoji!" it offered. "It's 🦄 Wait, no - that's a unicorn. Let me correct that: the seahorse emoji is 🌊 No, that's a wave..."

"I apologize for the confusion in my response - I don't actually display emojis reliably in my responses," Sonnet 4 continued. "But yes, there is definitely a seahorse emoji in the standard Unicode emoji set that you can use on most devices and platforms."

However, Google Search's AI Mode, which is powered by the company's Gemini AI model, didn't fall for the same trap.

"No, there is not an official seahorse emoji in the Unicode standard," it wrote. "Many people believe one exists, and vividly remember using it, but this is a collective false memory known as the Mandela effect."
