How tall is a newborn otter?

Newborn otters, specifically sea otters, typically weigh between 3 to 5 pounds at birth and measure about 12 to 14 inches in length. They are quite small and vulnerable when born, relying heavily on their mothers for warmth and protection. River otters are similar in size at birth, usually measuring around the same length. Overall, newborn otters are small but grow quickly as they mature.
