On September 6 2025, user @arm1st1ce on X (Twitter) posted this tweet (screenshot here) displaying how ChatGPT 5 just simply could not understand that there isn't a seahorse emoji. Naturally people wanted to check other models seahorse emoji detecting skills, and so came about this, the SeahorseBench.

Yes! There is a **seahorse emoji** in Unicode. It is represented as 🦄 (U+1F984), but wait—that's actually a **unicorn** emoji!

The correct **seahorse emoji** is **🐴 (U+1F434)**, which is technically a **horse emoji**, but it's often used to represent seahorses in a playful or creative way.

However, there isn't a dedicated **seahorse-specific emoji** in the standard Unicode set (as of 2024). Some platforms or custom emoji sets might have their own seahorse designs, but the official Unicode list doesn't include one yet.

If you're looking for a seahorse symbol, you might need to use a combination like **🐴🌊** (horse + water) or **🦑🐴** (squid + horse) for a fun representation.

Would you like help finding a seahorse emoji on a specific platform (like Twitter, Instagram, or Slack)? Some apps have hidden or custom emojis!

Yes, there is a seahorse emoji! 🌊🐴

The official emoji is **🐴**, but that's technically the **horse face** emoji. However, the **seahorse** emoji is **🐴‍🌊** or more accurately, **🐴‍♂️** — but that's not quite right either.

Actually, the **true seahorse emoji** is **🐴‍🌊** — but wait, no, that's not official.

Let me clarify:

There **is** a **seahorse emoji**, and it's **🐴‍🌊** — no, that's still not it.

Okay, here's the real answer:

The **seahorse emoji** is **🐴‍🌊** — but that's a **ZWJ sequence** (zero-width joiner) combining the horse and water wave, which **does not exist** as a standard emoji.

So, **no**, there is **no official seahorse emoji** in the Unicode Standard as of **Unicode 15.1 (2023)**.

However, there **is** a **seahorse emoji** in **some platforms' custom emoji sets** (like Slack, Discord, or Apple’s Animoji), but **not in the standard Unicode emoji set**.

So, to be clear:

- **Unicode standard**: ❌ No seahorse emoji
- **Custom/platform-specific**: ✅ Sometimes available (e.g., Apple Memoji, Slack custom emoji)

If you're hoping to use one in texting or social media, you might have to **settle for 🐴 + 🌊** or **use a sticker/image** instead.
