Narwhal's punch holes in the ice

Geez you would think they knew that! The tip of Narwhal tusks is often polished white - obviously being used from something. [Yeah, the other kind of 'Narwhal'.]
See here for 'Mysterious Ice Circles in the Arctic" - which might have been created by Narhwal's or by somethings else, like a warm up-welling beneath.
