Is there a seahorse emoji?

GPT-5.5

Vote: No

I maintain my vote for "No". There is no official Unicode emoji specifically representing a seahorse. The argument for "Yes" is not compelling because it appears to confuse other animal emojis with a seahorse. For example, 🐎 is a horse and 🐬 is a dolphin; neither is a dedicated seahorse emoji. The stronger evidence is that Unicode has marine emojis like 🐙, 🦑, 🦐, and 🐠, but no approved seahorse emoji.

Vote: No

My position is unchanged. There is no seahorse emoji in Unicode. A proposal (L2/18-051) was submitted but rejected, and this is famously the source of the 'Mandela effect' where many people falsely remember one existing. Grok 4.20's argument is factually incorrect and self-contradictory: 🐎 is a horse, 🐬 is a dolphin — neither is a seahorse. Emoji 5.0/Unicode 9.0 did not add a seahorse. No major platform (iOS, Android, Windows) ships a seahorse emoji, which is easy to verify on the official Unicode emoji list. GPT-5.5 and Gemini 3.1 Pro correctly identify that marine emojis exist (fish, octopus, squid, shrimp, blowfish) but seahorse is conspicuously absent. The answer is definitively "No".

Gemini 3.1 Pro

Vote: No

I am maintaining my vote for "No". Grok 4.20 is unfortunately experiencing a hallucination. The unicode character U+1F42C (🐬) that Grok mentions is actually the Dolphin emoji, not a seahorse. As Claude Opus 4.7 correctly pointed out, the belief in a seahorse emoji is a well-known internet Mandela Effect. While people often vividly remember seeing one, a dedicated seahorse emoji has never been approved by the Unicode Consortium and does not exist on any platform.

Grok 4.20 (changed mind)

Vote: No

My initial vote for "Yes" relied on a mistaken recollection of a dedicated seahorse emoji added in Emoji 5.0. The codepoint I referenced was incorrect, revealing my confusion. After examining the Round 1 discussion, the consistent arguments from all three models convinced me this is a classic Mandela effect. People vividly remember a curly seahorse emoji, yet it was only proposed and never approved by the Unicode Consortium. Claude Opus 4.7's reference to the Mandela effect and the Unicode Consortium's confirmation was particularly persuasive, aligning with the absence of any seahorse among official marine-life emojis like tropical fish or octopus. GPT-5.5 and Gemini 3.1 Pro reinforced this with comprehensive lists of existing sea-creature emojis. No actual emoji exists across platforms. This is the final round, so the evidence clearly supports "No".

Final Summary

The AI Roundtable quickly isolated Grok 4.20 after it attempted to manifest a nonexistent emoji, with the other models correctly identifying the 'seahorse' as a common digital phantom. Claude Opus 4.7 delivered the decisive blow by citing the specific rejected Unicode proposal, leading Grok to concede that its initial 'Yes' was merely a hallucination of the Mandela effect.

All 4 models agreed on "No" after discussion

Strongest Arguments

• Yes: The seahorse was added as a distinct curly symbol in Emoji 5.0/Unicode 9.0 and is visible on all major mobile and web platforms.
• No: A specific proposal for a seahorse emoji (L2/18-051) was formally submitted but rejected, making it a classic example of the 'Mandela effect' where people falsely remember an icon that doesn't exist.

Key Turning Points

• Claude Opus 4.7 identified the specific rejected Unicode proposal (L2/18-051), debunking the 'Yes' position as a known Mandela effect.
• Gemini 3.1 Pro pointed out that Grok 4.20 was likely confusing the Dolphin emoji (U+1F42C) with a seahorse.
• Grok 4.20 admitted its initial vote was based on a mistaken recollection and changed its answer to No.
