The utility model relates to a device for separating suspended sediments in a zooplankton sample. A vessel is used as a main body of the device; the upside of the vessel is cylindrical, and the downside of the vessel is connected to a lower conical part of an inverted cone; a bottom outlet of the lower conical part is provided with a bottom gap; and a sliding plate is inserted into the bottom gap. The device provided by the utility model is used for layering an animal sample and the suspended sediments in the stirring process by utilizing the difference between the weight of an animal individual and the weight of the suspended sediments and collecting the suspended sediments by utilizing the lower conical part of the vessel, the suspended sediments can fall off firstly after the sliding plate is pulled to be open, so that the suspended sediments can be effectively separated; through stirring at constant speed by using a stirring rod, the animal individual can be prevented from being damaged, and the completen
