Can you tell the age of an otter by the size of its paws?

The size of an otter's paws is not an accurate way to determine its age. Otters' paws do grow in proportion to their body size as they age, but there are several other factors that can influence paw size such as gender, species, and nutrition.

Instead, otter age can be estimated by examining their teeth or by observing their physical development and behavior. Otters have four distinct sets of teeth throughout their life and their teeth can give an indication of their age. Additionally, young otters are typically smaller and less developed than older otters, and their behavior can also give clues to their age, such as how they swim and how they interact with others.
