That’s a Scleral Ring and helps to keep the shape of the eye in fish, many reptiles, and birds. Fish don’t have round eyes (they’re shaped more like M&Ms or chocolate chips), and the ring helps support the shape when swimming. Most rings are just cartilage, but fast swimmers often have bony rings.
Not arguing with you, but what’s up with that “bone ring” they have in their orbit? We don’t have that.

Thank you, I had no idea that reptiles and birds have eyeball rings, too.
Based on this angle, I think you might be more correct. I thought it was recessed.
It’s a scleral ring. Lots of animals have that, many including humans don’t.
