The name of the Submarine, "Yakamoz" is essentially a word that has no direct equivalent in other languages. Yakamoz means the reflection of moonlight on delicate waves when the dark night sea catches the moonlight in the right angle and acts like a mirror. In Ottoman times it was believed the wriggling of fish was causing the gentle waves and thus creating yakamoz, therefore it was most often associated with fish. Yakamoz was also selected the most beautiful word in the world in a competition held in Berlin.
It is based on the 2015 novel, The Old Axolotl (Polish: Starosc Aksolotla) by Polish science-fiction author Jacek Dukaj. It is digital-only novel, meaning there was no printed edition published. It was translated to English by Stanley Bill. The book was nominated for the 2016 Janusz A. Zajdel Award. Axolotl is a Mexican salamander that in natural conditions retains its aquatic larval form throughout life but is able to breed. The word axolotl (Aztec origin, rendered. "ajolote" in Spanish) as a name means: water-slave, water-servant, water-player, water-monster, water-twin.
