Abstract
Gladioferens imparipes,a calanoid copepod from estuaries in Western Australia, displays behaviour and associated morphology which is unusual among calanoids. Adult and copepodid stages make temporary attachment to underwater surfaces using fine hair sensillae on the surface of the prosome. A clear pattern can be seen in the number and arrangement of hair sensillae in early copepodid stages. Line drawings, photomicrographs and an S.E.M. are used to illustrate the structures. Laboratory studies with live copepods in a flow chamber show that adult animals may hold position against water currents. It is hypothesized that this behaviour influences the distribution pattern in an estuary where low velocity tidally induced water movement occurs, and may be of value in enabling the copepod to exist beyond the distribution of a major predator.
