The Sediment Reworking of the Mud Shrimp <i>Laomedia</i> sp. (Crustacea: Laomediidae) with Tidal Conditions in the Intertidal Sediments of Gomso Bay, Korea

Although the thalassinidean mud shrimp <i>Laomedia</i> sp. is one of the most abundant species in the upper tidal flats along the west coast of Korea, little is known of its ecological characteristics and bioturbation effects on intertidal sediments. This study estimated the sediment rew...
