Researchers from Bergen University, Norway, have found that bearded gobies can survive low oxygen levels and recycle nutrients for other fish. The researchers studied waters off Namibia, where jellyfish and algae have infested a fishery. They found that the gobies are bottom dwellers in the day, surfacing at night. The gobies eat dead algae and jellyfish. Hake and horse mackerel eat gobies. This research was first reported in Science, DOI: 10.11261 science.1190708.
