"Sea urchins are currently the only animals that have been shown to see without having eyes. They see using light-sensitive cells in their tube feet, which resemble tentacles and, like the spines, are all over the body. You could say that the entire sea urchin is one single compound eye", says John Kirwan, who conducted the study as a part of his doctoral thesis, together with colleagues at Lund University.

They can register light with their "feet".

One of the few "animals", or whatever, that I won't eat. This just gives me another reason!

Only the females of sea ​​urchins are quality edible, or at least should be (if you don’t mind your food still moving around ... Yep.)
