A Shrimp Called Pee Wee by Janis Pacileo (2012)

When a new baby shrimp called Pee Wee is born, there is a hush in the sea. His mom and dad are concerned because he is tiny and his whole backside is shiny. The doctors and nurses work hard to save him. Then one day, they realize that something bigger than all of them has changed their sea, the place where they all live-and that change is responsible for Pee Wee’s unusual problems.
