Do butterflies drink turtle tears??

Yes I am a medical student.  No I don’t spend all my free time studying medicine.  Often I will begin my evenings with good intent, “I will read lectures A, B and C”.   Yet somehow along the way a ‘short’ study break will result in me knowing everything about great white sharks, “no I cannot tell you about about the spinothalamic tract, but did you know a their is a great white shark Lydia that has a twitter page?”


Anyways, a recent headline on my Facebook newsfeed (thanks National Geographic) has me wondering “Do butterflies really drink turtle tears??”

Turns out they do. Why? because turtle tears serve as a source of sodium (salt) for the butterflies, which have a harder time getting sodium because of their meatless diet (cute and functional!).  This is especially the case in the western Amazon, a location with limited sodium because of it’s far distance from the Atlantic ocean.  Curious of learning more?

“The important thing is to not stop questioning. Curiosity has its own reason for existence. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvellous structure of reality. It is enough if one tries merely to comprehend a little of this mystery each day.” -Albert Einstein
