Nematodes with five distinct forms found

(Phys.org)—An international team of researchers has found that at least one type of nematoad exhibits five distinct forms—each different enough that the microscopic worms were initially thought to be of different species. In their paper published in the journal Science Advances, the team describes their study of the worms that live in South Africa, Vietnam and on La Réunion Island and possible reasons for such diversity among a single species.
