What is the height of otters?

Otters vary in height depending on the species, but generally, they are low to the ground. For example, the North American river otter typically stands about 12 to 15 inches tall at the shoulder when on all fours. Sea otters, when on land, can be slightly taller, but they are also around the same height. Overall, otters are compact and agile animals adapted for life in water.
