We Are Dwarf Sperm Whales!

A Graphic Guide to Cetaceans

From the Series Anne Lambelet's Marine Life Graphic Guides

  • Interest Level: Grade 2 - Grade 5
  • Reading Level: Grade 2

All fins on deck! Kogi, a dwarf sperm whale, teaches us all about cetaceans, which also includes dolphins and porpoises.

Fun fact: the word cetacean comes from a Greek word meaning “sea monster,” but Kogi’s far too nice to be one of those. In fact, cetaceans are mammals (yep, just like humans). And they have lungs and breathe air—as do lions and tigers and bears! (Oh, my!) While dwarf sperm whales are the smallest type of whale, they have some really cool quirks. Their ink sacs help them evade predators, earning them the nickname “stealth whales.”

But we’re just scratching the surface! Join Kogi on a deep dive explaining why cetaceans are so special.

“On the way to school, a small whale with a big personality gets the lowdown from Mom on the whole cetacean clan.
It’s a good thing school isn’t too close, because Kogi (short for scientific name Kogia sima) has much to absorb about what makes whales distinctive from other creatures, the differences between toothed and baleen whales, and how the entire family descended not from prehistoric marine reptiles like mosasaurs, but from a cat-size land dwelling genus called Indohyus over the past 10 million years. The young enthusiast is thrilled to be a sperm whale, the largest of the toothed sort—but bummed when Mom offers a gentle correction. No, Kogi is a dwarf sperm whale, the smallest species of whale in the world. Worse yet, dwarf sperm whales don’t sing, nor do they swim as fast as dolphins. But, she consoles her fretful offspring, they are excellent echolocation hunters and suction feeders. Plus, along with their slightly larger cousins the pygmy sperm whales, they’re the only whales that can actually shoot ink out of their butts like squid to escape predators. “We’re stealth whales!” Kogi crows, high spirits restored. As in her book I’m a Dumbo Octopus! (2025), Lambelet fills her bright marine scenes with smiling but otherwise recognizably drawn sea life, peppers her work with a winning mix of humor and information, and closes with an actual photo of her effervescent, stubby-looking subject in the wild.
A fetching introduction that effortlessly delivers tons of fascinating facts."—Kirkus Reviews
