Researchers have discovered that the apple snail (Pomacea canaliculata) a freshwater mollusk can fully regenerate its camera-type eyes, which share key anatomical and genetic traits with human eyes, including a cornea, lens, retina, and optic nerve. The regeneration process unfolds over approximately 28 days, progressing through distinct stages: wound healing (within 24 hours), formation of a specialized cell mass, development of eye structures, and maturation. Critically, the gene pax6, known f
