They know how to bring the necessary tools to divers underwater: pincers, a hammer, a wrench, find objects that have fallen into the water, explore the seabed, deliver soil samples, find sunken ships, shells with pearls, detect fish schools and ships in distress, save drowning people. But that's not all! The secrets and secrets of dolphins will be revealed to you in our book!
