Toothed or Baleen? A Whale Compare and Contrast Book
Marine mammals known as cetaceans are broken into two large groups: toothed whales (including dolphins and porpoises) and baleen whales. One group has a single blowhole to breathe air, the other has two. One group has tall dorsal fins to help maintain balance as they chase prey. The other scoops up water and prey in their large mouths as they swim slowly along—they don’t need large dorsal fins. One group uses echolocation, the other doesn’t. Learn more about what these animals have in common and how they are different in this latest installment of the Compare and Contrast Series.

Author/Illustrator Info:

Cathleen McConnell lloves all animals—especially those that live in the ocean. Having the opportunity to share her excitement for other marine life with visitors is what inspired her to pursue a career in zoo and aquarium education. Currently, as part of her job with the Conservation Engagement team at the Point Defiance Zoo & Aquarium, Cathleen runs all kinds of family programs including day camps and “Zoo Snooze” overnight experiences. Over the years she has taught countless children about the wonders of wildlife when they have visited on field trips, or as part of an outreach program at their school. In addition to writing curriculum for teachers, Cathleen has also written Otters: River or Sea? A Compare and Contrast Book for Arbordale. She hopes the books will get kids excited to learn more about animals and how each is uniquely adapted to survive in their natural environment. Cathleen lives in Washington state with her three cats and two guinea pigs. When she can, she also fosters guinea pigs in need of adoption through a local rescue group.
