Do Sea Lions Have Tusks?

Question For Our Viewers:

We recently saw this tusk auctioned at an online auction website: 150 year old Sea Lion Tusk.  Is this for real?

We've never seen a sea lion tusk. Have you? If you have, please let us know, because we are bewildered by this information.

We not saying this "sea lion tusk" is illegal, but we would like to remind everybody about The Lacey Act of 1900 and to always be aware of Caveat Emptor!

However, seriously, we really would like to know if sea lions have tusks, and if they do, are they ever this big?
