The walrus is a sea animal with a not-so-pleasant appearance. But they were hunted for their tusks, meat and skin. They have long ivory tusks just like elephants.
The tusk of a walrus is soft enough to be carved to any shape, but sturdy enough to stay for a really long time. Because of this, walrus tusks were used to make jewellery in the past. Wonder what the tusk is made of? The ivory tusk of a walrus is made of a protein, a polymer which makes our hair and fingernails. The protein provides longevity and softness lo the tusk. Now, we have a lot of alternatives for jewellery and this poor creature is largely spared.
