Streszczenie: The subject of investigation were morphological changes in the marine planctonic animals, Chaetognatha (arrow worms), exposed to anthropogenic radiation. The animals were taken in the epicentre of the radioactive spot of the Chazhma Bay (the Sea of Japan). Morphological deviations were determined under a hand magnifying lens and a microscope, while tissue changes were studied on histological sections. The studies have revealed that radiation causes damage to the skin epithelium, changes in fin plates, separation of the skin epithelium from muscles, separation of teeth apparatus from the body surface, damage to the intestine. These changes are characteristic solely of radiation pollution and are not encountered under any other damaging effects such as those of geophysical factors, heavy metals pollution, influence of ultrasound. Anomalous animals preserve their viability, and this makes it possible to use the chaetognaths for the bioindication of radiation pollution of marine waters.
