This dredge is useful for sampling benthic communities inhabiting soft bottomed aquatic environments. As the dredge is lowered, the hinged upper doors swing open, allowing water to pass through and minimize the shock wave. When the dredge reaches the bottom, a messenger is sent down the line which trips the spring-loaded jaws. The jaws snap shut, preventing washout of the sample.
