The chiton, a kind of marine mollusk, was found with eyes in its shell in 2015 by a Harvard and MIT science team. Ling Li and some other researchers from the team studied a specific type of chitin called, scientifically, Acanthopleura granula. They have "lenses with mineral bases that are scattered across its armored shell." Each lense is less that one tenth of a millimeter in size.
Tests were done in the Argonne National Library. The science team performed high-resolution X-Ray tomagrahy tests that allowed them to be able to see the eyes. The team believes the eyes are mostly for protective purposes, to keep themselves safe from predators.
I think this is very interesting because it goes to show how much there is about the natural world that scientists do not know yet. I think it is amazing that these organisms were thought to have existed without eyes, and were discovered to be able to see. It is a representation of how much there still is to uncover in the natural world.
