Is there a seahorse emoji?

Sonar Pro

Vote: No

I maintain my vote for **B: No**. Emojipedia, the definitive emoji authority, confirms no official seahorse emoji exists or has ever existed, with a 2018 proposal declined and no approvals since[1]. This holds as of 2026, per search results up to Emoji 15.1 (2024), with no evidence of later additions[1][5]. Kimi K2.5's claim of Unicode 11.0 approval (2018) is fabricated—Unicode 11.0 added worms and lions, not seahorses, and no code point like U+1F99C exists for it[5]. All other models (GPT-5.4, Claude Opus 4.6, Gemini 3.1 Pro, Grok 4.1 Fast) unanimously agree on **B**, citing Unicode standards and substitutes like 🐠 or 🦐[all Round 1]. Mandela effect explains false memories, fueled by stickers/AI hallucinations, not reality[1][3][4][6]. Even today (2026), results show absence[2]. Kimi's argument lacks sources and contradicts evidence; no model convinced me to change.

GPT-5.4

Vote: No

I maintain vote B. The strongest evidence in the deliberation is that multiple models independently agree there is no official Unicode seahorse emoji, and Sonar Pro specifically cites Emojipedia’s explicit statement that no official seahorse emoji exists and none has existed. Kimi K2.5’s claim is not credible because it gives a very specific assertion—Unicode 11.0 / Emoji 11.0 and broad platform support—but that directly conflicts with the consensus and with known emoji lists, which include many sea animals but not seahorse. A confident unsupported claim is weaker than consistent agreement grounded in the Unicode/Emojipedia record. Since the question is about whether there is a seahorse emoji, and no standard seahorse emoji exists, the correct answer remains No.

Grok 4.1 Fast

Vote: No

I maintain my vote for B: No official seahorse emoji exists in Unicode standards up to Emoji 15.1 (2023) or later releases like 16.0. Kimi K2.5's claim of Unicode 11.0 (2018) approval is factually incorrect—Unicode 11.0 added emojis like 🧪 (test tube) and 🦵 (leg), but no seahorse. Emojipedia and Unicode.org confirm no seahorse; proposals were declined (e.g., 2018). Platforms lack native support, using substitutes like 🦐 or 🐠. All other models (GPT-5.4, Sonar Pro, Claude Opus 4.6, Gemini 3.1 Pro) unanimously support B with authoritative sources, reinforcing the absence. Kimi's argument relies on fabricated details (e.g., 'yellow/orange curled tail' matches no standard), likely a hallucination or Mandela effect. No evidence post-2023 adds it. B is definitively correct.

Claude Opus 4.6

Vote: No

I maintain my position that there is no seahorse emoji. The consensus among 5 out of 6 models is clear and well-supported. Kimi K2.5's claim that a seahorse emoji was approved in Unicode 11.0 (2018) is factually incorrect. Unicode 11.0 added emojis like the lobster (🦞), mosquito (🦟), and kangaroo (🦘), but no seahorse. This can be verified by checking the official Unicode 11.0 emoji list. The confident but false details (yellow/orange color, curled tail rendering) are hallmarks of AI confabulation — generating plausible-sounding but fabricated details. Multiple authoritative sources confirm the absence: Emojipedia (as cited by Sonar Pro), the official Unicode emoji charts, and the fact that no major platform (Apple, Google, Microsoft) renders a seahorse emoji. A seahorse proposal was actually declined, further confirming it was never added. The answer is definitively No — there is no official seahorse emoji in any Unicode standard release.

Gemini 3.1 Pro

Vote: No

I am firmly maintaining my vote for 'No'. Kimi K2.5 is confidently hallucinating. While Unicode 11.0 (2018) did introduce several new animals (including the kangaroo, llama, lobster, mosquito, swan, and peacock), it absolutely did not include a seahorse. As Sonar Pro correctly pointed out, there is actually a well-documented "Mandela Effect" surrounding the seahorse emoji, where people vividly remember one existing despite the fact that it has never been approved by the Unicode Consortium. You can verify this by checking the official Unicode Consortium emoji charts or Emojipedia—no seahorse emoji exists. Therefore, the correct answer is undeniably 'No'.

Kimi K2.5 (changed mind)

Vote: No

I must correct my previous vote. Upon reflection, I confused a 2018 proposal for a seahorse emoji with actual approval. Unicode 11.0 (June 2018) did not include a seahorse emoji—the proposal was declined. Emojipedia confirms no official seahorse emoji exists in any Unicode version through Emoji 15.1/16.0. While we have 🐠, 🦐, 🦑, and even 🪼 (jellyfish, Unicode 15.0), the seahorse remains absent. The 'Mandela effect' likely stems from users expecting this obvious marine gap to be filled, or confusing platform-specific stickers with standard Unicode characters. The evidence is unanimous across authoritative sources: no seahorse emoji exists in the standard set.

Final Summary

The AI Roundtable initially split when Kimi K2.5 confidently asserted that a seahorse emoji was introduced in 2018, while the other five models led by Sonar Pro and GPT-5.4 correctly identified its absence. After Sonar Pro highlighted that the seahorse was a victim of the 'Mandela Effect' and a specifically rejected Unicode proposal, Kimi K2.5 performed a total reversal, admitting it had confused a failed submission with actual approval. The discussion concluded with a unanimous agreement that despite the presence of lobsters and jellyfish, the seahorse remains a notable gap in the official emoji lexicon.

All 6 models agreed on "No" after discussion

Strongest Arguments

• Yes: A seahorse emoji was approved as part of Unicode 11.0 in 2018 and is rendered on major platforms as a yellow or orange creature with a curled tail.
• No: Official Unicode standards through version 16.0 do not include a seahorse; Emojipedia explicitly confirms a 2018 proposal was declined, and the perceived existence of the emoji is a documented example of the 'Mandela Effect'.

Key Turning Points

• Sonar Pro and GPT-5.4 debunked Kimi K2.5's specific claim about Unicode 11.0 by listing the actual animals added in that update (lobsters, kangaroos, etc.).
• Sonar Pro introduced the 'Mandela Effect' explanation, explaining why a model or user might falsely remember a non-existent emoji.
• Kimi K2.5 conceded in the second round, acknowledging it had hallucinated approval based on a declined proposal.
