Rotifers

Indeed, they are called rotifers, because of their unique way of locomotion. ❋ Joyce Whiteley Hawkes (2006)

In some of the lower forms, as in rotifers, insects, and crustaceans, are found the most inferior males, often none at all; and, where they do exist, they have no use save as an agent in reproduction. ❋ Unknown (1898)

Tiny organisms called rotifers and copepods, meanwhile, consume bacteria, cleaning out pathogens like salmonella. ❋ Unknown (2007)

Technically, it is probably a misnomer to call my rotifers "guys," especially if they are bdelloid rotifers, which are only female. ❋ Unknown (2009)

In general, the abundance and diversity of phytoplankton and invertebrates such as rotifers, copepods, and cladocerans increase with lake trophic status [59], which is often a function of latitudinal constraints on resources for productivity. ❋ Unknown (2009)

From a simple accumulation of pigment-cells which serves to arrest light rays (in simple organisms such as rotifers) to that complex and beautiful structure -- the human eye -- the organs of vision have been developed, step by step. ❋ James Weir (1881)

The authors base this claim on the well known fact several groups of multicellular animals, for example, bdelloid rotifers, tardigrades, nematodes and arthropods, have representatives that can survive extreme desiccation for long periods. ❋ AYDIN (2009)

Mertens et al. showed that the seeds or spores of various plants (Cardamine, Taraxacum, Adiantum, etc.), the cysts of the crustaceans Branchipus schaefferi (fairy shrimp) and Artemia franciscana (brine shrimp) as well as adult bdelloid rotifers and tardigrades survived exposures to temperatures as high as 130 °C for as long as 10 min. ❋ AYDIN (2009)

 Male rotifers show a distinct preference for fertilizing very young females two to three hours old which slightly improves the likelihood of fertilizing a sexual female, although they do not specifically discriminate between sexual and asexual individuals3. ❋ Carin Bondar (2012)

If desiccated rotifers and tardigrades or the seeds and spores of various plants are routinely exposed to temperatures around 40 °C, then those individuals that have evolved to incorporate a safety factor into their adaptation that makes them survive slightly higher temperatures, say 50 °C, will fare better in the long run when and if the habitat temperature happens to rise that high. ❋ AYDIN (2009)

This paper came to my attention because it cites one of my old papers on bdelloid rotifers (Örstan, 1995). ❋ AYDIN (2009)

Bdelloid rotifers (class Bdelloidea), with about 350 or so known species, are the largest group of animals that reproduce exclusively by parthenogenesis. ❋ AYDIN (2009)

There are other creatures which can survive extreme dryness—rotifers, nematodes, brine shrimp. ❋ Lou Anders (2010)

Those are the Bdelloid rotifers, which number over 300 species. ❋ Unknown (2010)

[Husband] has sex with another woman after work; not long after, [husband] proceeds home to [meals] [prepared] by wife and wife realizes nothing, thus rotification is achieved. ❋ Naughtypunjabi (2009)
