Very well told story about how phytoplankton are the starting point for the chain of life in the seas. My niece was particularly interested in this book, and was quite taken aback to learn that the "green" in our seas is everywhere (in the form of phytoplankton). Both children were completely disgusted by marine snow (my nephew exclaimed, "WHAT?! There's poop
in it?! Fish eat other fishes' poop
?! That's disgusting!! WHO WROTE THIS BOOK?!"). I, however, was quite pleased that the author didn't sugar coat what marine snow is comprised of, because I know that single fact will stick with the kids. Because that fact will stick with them, the rest of the facts in this book will necessarily have to be called to mind, as well. Molly Bang did an excellent job with this book, and I'm just not sure the story of phytoplankton could have been told to kids any better than they told it.
