Environmental police are alarming

According to ahooita.com
Batiscaf Jacques-Iva-Cuccott, during his first expedition, barely stifled a sea pig.

According to his first book, In the World of Silence, Kusto began to dive into the water using a mask, a tube, and lashes.

Before it became known about the ability of sea pigs to echo-locate, Custo suggested the possibility of its existence. In his first book, In a World of Silence, he that his research vessel "Élie Monier" was heading towards the Strait of Gibraltar and noticed a group of pigs following them. Kusto changed the course of the ship by a few degrees from the optimal, and the pigs followed the ship for a while, and then sailed to the center of the strait. It was obvious that they knew where the optimal course lies, even if people did not know. Custo concluded that whales have something like a sonar, which was at the time a relatively new element on submarines. He was right.
