摘要：

The hydrodynamic properties of U-tubes, simulating the burrows of thalassinid prawn, Upogebia africana Ortmann were examined. Flow was induced through the U-tube as a result of a reduced pressure gradient set up by the external stream as it passed over a cone-shaped elevation, the Bernoulli effect, and was proportional to tube Reynolds number and its aspect ratio. Animals within their artificial burrows showed a significant orientation (P<0·05) towards an induced current, and a significant reduction (P<0·05) in the time spent actively pumping water through their burrows. These results suggest that the currents induced through the natural burrows from the tidal flow overhead play an important role in the feeding and respiratory behaviour of these animals. © 1992 Academic Press Limited.
