Apple snails can regrow their eyeballs

Breakthroughs, discoveries, and DIY tips sent every weekday. If you step on a snail, you'll know it. Despite their slow speeds, and simple bodies, apple snails (Pomacea canaliculata) have eyes that are anatomically similar to human eyes. Both species have complex camera-like eyes with a lens, cornea, and retina that visually capture the world around them. Unlike humans, apple snails can regrow their peepers if they are injured or amputated.
