The rotifers of Heard Island: Preliminary survey, with notes on other freshwater groups

Twenty rotifers (three Bdelloidea and 17 Monogononta, including new species of Encentrum and Notholca), a platyhelminrh, gasrrotrich, two nematodes, two tardigrades, one enchyrraeid worm, four cladoccrans, rwo copcpods and three species of mites were recovered from five small pools on Heard Island. The results indicate that the Heard Island fauna is closer to chat of Signy Island and Macquarie Island than to that of the much nearer Kerguelen archipelago.
