"Frog eyes!! Frogs may be well-known for their jumping skills, croaking, and slimy skin, but their eyes are seriously impressive! Eyes are such complex sensory organs, and frog eyes have several characteristics that make them even more amazing! Most frogs have large, bulging eyes that are positioned on top of their heads. The size and position of their eyeballs gives them close to a 360 degree field of view and compensates for their inability to turn their heads. Their eyes also have a nictitating membrane, which is like a semi-transparent eyelid that protects and camouflages their eyes. Frogs have powerful night vision, thanks to a mirror-like layer of tissue behind their retinas, called the tapetum lucidum, which makes their eyes appear to glow in the dark. It helps them see objects in low light. And, if their eyes get damaged, they can regenerate the different structures and self-repair! Amazing! One of the most strangely cool things about frog eyes is that they help with eating. Frogs don't have the muscles needed to chew and swallow their food. So, when a frog swallows, its eyes retract into openings in their skull, push the food down its throat, and help it to swallow! Eyes are amazing organs. Just the fact that all the components in an eyeball work together so that we can see the world around us is astounding! The diversity of frog eye color and patterns, in addition to their special features makes frog eyes truly exceptional. {Credits are in the comments} #JungleDragon" Posted 6 years ago
I feel really stupid for not knowing that frogs can't turn their heads. It makes total sense in hindsight but I never put any thought into it.
Eyes helping to swallow food was an even greater eye-opener ;) Posted 6 years ago
