Rotifers in saltwater environments, re-evaluation of an inconspicuous taxon

Rotifers are microscopic aquatic animals that comprise more than 1800 species. Most rotifer species live in freshwater and limno-terrestrial habitats, while thalassic environments (brackish+seawater) are thought to host few species. No recent review of saline rotifers is available. Here we report the results of a review of the literature concerning rotifers from saline environments, distinguished into three categories: stenohaline, euryhaline, and haloxenous, and found both in truly marine habitats and/or in inland saline waters. A total of about 200 studies, mentioning fully identified rotifers from saline waters, allowed us to list as many as 443 rotifer taxa at either specific, subspecific and infrasubspecific rank, corresponding to 391 nominal species. Truly thalassic taxa, not found in inland saline waters only, accounted for 289, including the ‘stenohaline’ (143) and the euryhaline (146) ones. As for freshwaters, the majority of the thalassic rotifers inhabit the psammon, or display a benthic–periphytic way of life, while the plankton likewise is less species rich and less abundant. The geographical distribution of the brackish and marine rotifers largely reflects the distribution of rotifer investigators, therefore, no biogeographical analysis can be performed yet. In conclusion, the analysis of literature citing rotifers in salt waters, uncovers an unexpected rotifer fauna: the apparent richness of the group in thalassic environments is worthy of being addressed by further investigations, as many species have been reported only by their description, suggesting either considerable endemism or taxonomic errors.

“…For example, from Crozet just four genera of rotifers (Cephalodella, Lecane, Lepadella and Proales) have been recorded, identified from the gut contents of the predatory freshwater amphipod Pseudingolfiella possessionis (De Smet 2015). Interestingly De Smet (2002a) recorded nine species from the littoral zones of both Îles Kerguelen and Crozet. This habitat is outside the scope of this paper but two of the species De Smet found (Colurella colurus and Lindia torulosa) are frequently found in freshwater and as such have been added to table 1 as interlopers.…”

The metazoan fauna of Antarctic and sub-Antarctic freshwaters is reviewed. Almost 400 species, notably rotifers, tardigrades and crustaceans have been identified. Sponges, molluscs, amphibians, reptiles and fishes are absent though salmonid fishes have been successfully introduced on some of the sub-Antarctic islands. Other alien introductions include insects (Chironomidae) and annelid worms (Oligochaeta). The fauna is predominately benthic in habitat and becomes increasingly depauperate at higher latitudes. Endemic species are known but only a few are widely distributed. Planktonic species are rare and only one parasitic species has been noted.

Two new species of rotifer belonging to the Dicranophoridae, and provisionally placed in the genus Encentrum, are described from littoral psammon from the Ussuriyskiy Bay, Peter the Great Bay, Sea of Japan, Russia. Encentrum kutikovae sp. nov. is characterized by a long foot consisting of three pseudosegments, cylindrical toes, a hexagonal rami outline, and the right ramus showing an accessory chamber with alula. Encentrum ussuriensis sp. nov. is characterized by unusual stout toes with claw, an oblong-ovate and latero-caudal weakly angular rami outline, the right ramus bearing an alula, and the left one showing an accessory chamber.
