Additions to the freshwater fauna of Heard Island

Freshwater collections from Heard Island yielded a fauna of protozoans, one species of platyhelminth, two species of tardigrades, at least four species of nematodes, 16 species of rotifer (including two new species and four new records for the island), one species of enchytraeid worm, and nine species of arthropod (four anomopodans, two copepods and three mites). No ostracods were found, nor was any evidence of insects with aquatic or semi-aquatic larvae.
