Beautiful pests Jellyfish are on the rise throughout the oceans as man kills off the fish that keep them in check through competition and predation, according to recent research. Some of these
changes are described in a study in the June 8 issue of the journal Trends in Ecology and Evolution. "Mounting evidence suggests that open-ocean ecosystems can flip from being dominated by fish, to being dominated by jellyfish," said Anthony Richardson of the University of Queensland, Australia, one of the
scientists. "This would have lasting ecological, economic and social consequences." Above,
