At least one , Cirolana harfordi, exhibits gregarious aggregative driven by attraction and negative . This species has been observed to congregate under shelters, with formation influenced by both social and environmental factors. Some species swim out from under rocks at high tide to forage.

Human Relevance

Some have been named for notable figures, including C. mercuryi for musician Freddie Mercury and C. brucei for isopod taxonomist Niel L. Bruce. Cirolana borealis has been used in studies of radionuclide biokinetics. C. capricornica has been recorded from fish (Epinephelus chlorostigma), suggesting potential ecological or fisheries relevance.
