Sea ivory refers to the teeth of walrus in the Arctic Ocean, which can be carved as works of art, such as boxes and pendants. Sea ivory mainly comes from the sea near the Arctic Ocean.

The long teeth (maxillary fangs) of Odobenidae in Pinpoda are generally 0.5 ~ 1 m long, with three flat petals in cross section, mostly pale yellow and cream-colored. Their texture is rougher than that of ivory and hippopotamus teeth, and their inner core is loose, which is close to ordinary bones.

Walrus population status

Walruses are also particularly sensitive to changes in the marine environment. Due to the large-scale exploitation of oil and natural gas, many walruses' habitats are polluted, so that they cannot survive and become extinct, and their distribution area is gradually shrinking.

With the increasing demand for sea ivory, the walrus hunting industry is also developing, and the hunting tools and methods are constantly improving and perfecting, which has caused a devastating blow to the living conditions of walrus. The number of Arctic walruses in Russia has dropped sharply, from millions two or three centuries ago to less than 70,000. The total number of walruses of all subspecies will not exceed 400 thousand.
