A coloring book. 

Fast and smart dolphins rightfully deserve to be considered the smartest marine animals. And maybe not just marine ones! It turns out that dolphins recognize themselves in the mirror, give each other names, and help their weak relatives. They can bring the necessary tools to divers underwater: pliers, a hammer, a wrench, find items that have fallen into the water, scout the seabed, deliver soil samples, locate sunken ships, shells with pearls, detect schools of fish, and rescue distressed vessels, saving drowning people. But that's not all! The mysteries and secrets of dolphins will be revealed to you in our book!

Interesting facts:

• Every 30 seconds, a dolphin surfaces to take in air.
