What are Walrus Tusks Made Of?

Walrus tusks are actually elongated canine teeth that can grow to be several feet long. These impressive tusks are made primarily of dentin, which is a hard tissue similar to the enamel on human teeth. Dentin makes up the majority of the tusk's structure and gives it its strength and durability.

In addition to dentin, walrus tusks also contain a small amount of cementum and enamel. Cementum is a hard tissue that covers the root of the tusk and helps anchor it in the walrus's skull. Enamel, on the other hand, is a hard, mineralized substance that covers the outside of the tusk and provides an extra layer of protection.

Walrus tusks are constantly growing throughout the animal's life, with males typically having larger tusks than females. These tusks serve a variety of purposes, including foraging for food, digging in the sea floor for clams and other prey, and establishing dominance within the walrus population.

Due to their impressive size and unique composition, walrus tusks have been highly valued by humans for thousands of years. In some cultures, walrus tusks are used for making tools, weapons, and decorative items. They have also been used in traditional medicine and as a symbol of wealth and status.

It is important to note that the trade of walrus tusks is heavily regulated to protect these magnificent creatures from over-harvesting. In many countries, it is illegal to buy or sell walrus tusks without the proper permits and documentation.

In conclusion, walrus tusks are made primarily of dentin, with small amounts of cementum and enamel. These impressive structures play a crucial role in the walrus's daily life and have been highly valued by humans for centuries. By understanding the composition and importance of walrus tusks, we can better appreciate and protect these amazing animals.
