In the most arid areas where there is little to no water, there live nematodes of no more than 1 mm which feed on bacteria and help to mineralise soil and produce nutrients. In an orchard of Jaén a new species has appeared with a feature that makes them unique on the Iberian Peninsula: the males lack the copulatory organ.
