Summary Most ectothermic organisms become immobile at a few degrees above zero. The unicellular planktonic algaeDunaliella sp., andChlamydomonas sp. from Antarctic hypersaline lakes remain motile at temperatures as low as −14 °C.Pyramimonas gelidicola from the same habitat stops swimming at −10 °C but its flagella continue to beat at −14 °C. Further, the characteristic shape ofPyramimonas, which is maintained by cytoskeletal microtubules, is unaffected by such low temperature.
