Learned that sea urchins have a single eye and now I'm physically ill

[Two photos, the first showing a sea urchin and the second more zoomed in on a small orange part in the middle of its body.]

Readers added context
That is a butthole.

Any marine biologists able to weigh in?

Not a marine biologist, but I am a biology student in my undergrad, and have dissected these recently. That is indeed the butthole. Sea urchins don't have eyes.

I have no eyes but I must poop.
