Octopus ink has been found to cure cancer.

Mexican scientists have discovered a molecule in the ink of common octopuses that destroys tumors without harming healthy cells. It was synthesized artificially and named ozopromide (ozopromide). The new molecule slowed down the growth and reproduction of tumor cells, which caused them to die en masse. Their number was halved, while healthy cells were not damaged by ozopromide. Perhaps, on its basis, it will be possible to create more benign methods of treating cancer.
