When their relaxing sea vacation is interrupted, Jake, Sherry, Kwame and the rest of Dr. Darwin's X-Venture X-plorers head under the sea to find out all about creatures from the deep. And under the sea, sharks are king. But the sharks are not the apex predator they once were, illegal fishing is harming their lives and habitat. Learn about the various species of sharks, tooth by tooth, and find out who would win in a hypothetical battle between fishes, and who would end up as chum. Each comics chapter is followed by an informative prose chapter, filled with exciting facts and illustrations about the real-life creatures featured in the comics.
