How many teeth do they have? At any one time, it can be about seven per quadrant. Usually calves have four teeth per quadrant, and as they get larger they may have seven in each quadrant. But over a lifetime,the number changes, because that rate of movement is different depending on their diet, and how much sand is in the area where they're feeding, and how coarse the vegetation is if they're feeding on coarse grasses you know their teeth are going to migrate more quickly than they would if they're just feeding on soft freshwater vegetation most of the time.

In comparison to other mammals' teeth, Manatee teeth are very unique. Rather than having one tooth fall out and then be replaced in the same spot with another (vertically), Manatee teeth are just continually replaced horizontally (marching molars). Tooth replacement continues throughout their life.
