Research Abstract

Decapod callianassid shrimps reside in deep burrows in marine soft-sediment habitats and exclude bivalves through their bioturbating activity causing substrate surface destabilization. However, these processes and mechanisms have yet to be examined. It was revealed for a system comprising the shrimp (Nihonotrypaea harmandi) and the gastropod (Umbonium moniliferum) on an intertidal sandflat in Amakusa, Kyushu that adults of the former expel sediment out of their burrows in response to its inflow due to transport by tidal currents and waves and that larvae of the latter are prevented from settling on the substratum by blowout flows from shrimp burrow openings.
