The snail with the right heart : a true story
Maria Popova (Author), Ping Zhu (Illustrator)
This is the real-life story of Jeremy, a rare garden snail found in 2015 by a retired London scientist. Jeremy's shell spiraled to the left, indicating reversed internal anatomy--including a heart positioned on the right. As a result, a similarly rare mate was needed in order to procreate.-- Source other than the Library of Congress
