A hybrid population of threespine stickleback and Japan Sea stickleback discovered in this pond ... the marine Japan Sea stickleback was carried into the freshwater pond by the tsunami, while the freshwater threespine stickleback was carried from upstream by the backwash. The two species came into contact, resulting in interspecific hybridization.
