We Are Dwarf Sperm Whales!

It’s the first day of school, and Mom is escorting Kogi (a nod to Kogia sima) there. Along the way, Kogi learns about cetaceans: who else is part of the family, their evolution, their differences and similarities to other fish and land animals. Discussion turns to notable cetacean characteristics, but these don’t apply to Kogi. Dwarf sperm whales are not the biggest; they are not known for singing; they are not the fastest; they don’t have the largest pods; and they are not the most agile. As Kogi grows more disappointed, Mom reveals what makes dwarf sperm whales unique: their use of echolocation, their ability to suck prey from the ocean floor, their high-frequency communication clicks, and their ability to ink predators.

Kogi’s anthropomorphic characteristics (wanting to sleep in a little longer), and humor (some more subtle than others) helps keep young readers (even those who know a lot about whales) engaged. The graphics add to the humor and enhance learning. The narrative has great subject matter breadth and just enough depth to not be redundant to even the most advanced young readers. Most adults may also learn a thing or two. Highly recommended for readers in grades 1-5, especially those interested in marine life.
