Abstract
Fertilized eggs of the clawed toad Xenopus laevis were placed aboard of orbital laboratory of "Salut-6" spacecraft where they developed for 20 days at temperature 15 degrees C. The larvae were fixed in weightlessness. Light and electronmicroscopic studies revealed undisturbed structure on the saccular and utricular maculae and otolith membranes. Some ultrastructural abnormalities were found in the inner ear of adult rats after 20 days of weightlessness ("Kosmos-936").
