This Fish/Mermaid Optical Illusion Is Dividing The Internet (Because The Caption Is Lying To You)

I see a seal first. Then I see a donkey. I can even understand that some people might see a fish. But a mermaid? No. <3

It feels like it's been a minute since we last fought about a viral optical illusion, and while this one is no Dress™, it is sparking a conversation over on Twitter.

The illusion looks like this, and if the caption is to be believed, right-brained people are likely to see a fish, while left-brained people are more likely to see a mermaid.

The issue is: a lot of people, including me, see neither a fish nor a mermaid. They see either a donkey or a seal.

Tell the truth. Does anyone actually see fish to a mermaid? Anyone?

Nick Offerman, for example, sees a donkey.

This person, on the other hand, is adamant about it being a seal. (I agree, FWIW.)

They’re called seals and it’s clear if you use your whole damn brain.

It turns out that the image is actually of an "ambiguous horse–seal figure" that's been used in scientific studies of visual perception — so if you saw a fish or a mermaid, joke's on you, my friend.

@JasonIsbell I see the seal/horse, or fittingly "source".

(And if you saw a horse, you're just wrong. It's a seal.)
