Okay, I thought that they were like clams and the picture at the start of the article was showing a row of eyes between the fuzzy/spiky stuff on the side but after looking them up, that shiny part between the fuzzy/spiky stuff in the picture is it's shell. The eyes are tiny specs between all the fuzzy/spiky stuff.
I still don't know WHY they have eyes all over their shells even after reading the article. It's a pretty click baity title, but I guess it worked on me so they won this round.
What's click baity? They literally have eyes all over their shells. The article goes into the 2 main eye types they've evolved, when they evolved them, and supposes it's to avoid getting eaten which is a pretty reasonable theory.
I guess the "sea creature mystery" is a bit click baity but not the eyes all over it's shell part.
Look up pictures of chiton (the name of the creature in question). It's nearly impossible to find a picture that looks like the shell itself are the eyes, yet in the article featured front and center is a picture of a chiton with a shell that happens to look like bug eyes.
