How long can a female narwhal tusk grow?

A female narwhal typically does not grow a tusk, as this characteristic is primarily found in males. However, in rare cases, some female Narwhals may develop a small tusk. When present, the tusk can grow to lengths of about 4 to 8 feet, similar to that of male narwhals, which can reach lengths of up to 10 feet. The tusk is actually an elongated tooth and serves various functions, including social signaling and possibly sensing the environment.
