Gladioferens imparipes lives in estuarine waters of a wide range of salinity. However it often has a much more restricted distribution; in the Swan River estuary of Western Australia it is only plentiful in low salinity water. It is seldom present where either of two less euryhaline species, Sulcanus conflictus or Acartia clausi, are abundant. These two species prey on young larvae of Gladioferens. When these predators are present in high density they may eliminate their prey, Gladioferens nauplii. Gladioferens is then restricted to parts of the estuaries where environmental conditions are unfavorable to Sulcanus or Acartia.
