Replica Narwhal Tusk with Base
The narwhal is found in the extreme northern Atlantic and Arctic oceans. This species possesses a long spiral tooth that projects like a horn and can reach a length of 9 feet (3m) in males. During the middle ages, the tusk of the narwhal was considered proof of the existence of the unicorn. This species lacks functional teeth for feeding but uses a suck and gulp technique to dine on shrimp, squid, and fish.
