Hi there! Did you know that narwhals have really long tusks that look like big spirals coming out of their heads? These tusks are actually special teeth that grow really long. Narwhals like to keep their tusks clean so they can stay healthy!
One way they clean their tusks is by rubbing them together. Imagine two long sticks rubbing against each other — this rubbing helps scrub off any dirt or little animals that might be stuck. It's like when you rub your hands to get them clean.
This is a smart way for narwhals to take care of their important tusks while they swim in the cold ocean water. So next time you see a picture of a narwhal, remember that their tusks are not only cool but also get a special cleaning by rubbing them together!
