Abstract

From the word go till nowadays, laboratory biologists have been focused mostly on a few practical biological models, which largely determined and narrowed down our modern vision of diverse complex physiological cellular and molecular bioprocesses. The choice of model organism is an important issue in experimental biology, particularly, in space exploration biomedical science. Largely unknown non-classical aquatic model organisms will be advantageous for further developments on the path of humanity into space. Selected perspective hydrobiont models based on old almost-forgotten and new literature data are discussed that could be of future use in the expanding biomedical space science.
