Why is a Deepsea Flounder as flat as a pancake? Why does the Prickly Footballfish have a fishing rod-like light on its head?

Dive deep through the ocean zones to discover some of the most unusual creatures from the sea, and find out why they have come to look and behave the way they do.

The first book in a new picture book series about unusual animal evolution stories, from award-winning and best-selling author and illustrator, Sami Bayly.
