rotifers

Indeed, they are called rotifers, because of their unique way of locomotion.

Cell-Level Healing 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.

Tiny organisms called rotifers and copepods, meanwhile, consume bacteria, cleaning out pathogens like salmonella.

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

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.

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.

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.

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.

 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.

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