The existence of the species is quite a debatable topic as very little information is available as of now.
The only living species in the family Odobenidae and the Odobenus genus, the walrus consists of two subspecies, Atlantic walrus (Odobenus rosmarus rosmarus) and Pacific walrus (Odobenus rosmarus divergens). The subspecies are found in the Atlantic and Pacific Oceans, respectively.
Walruses are best known for their tusks or enlarged canine teeth that can easily break through 8 in (20 cm) of ice. They also possess whiskers that provide additional sensory information.
The skin of walruses is either light gray or yellowish-brown in color. The average weight of the species is around 1323-3307 lb (600-1500 kg), while they are 6.6–11.5 ft (2-3.5 m) long. The Pacific walruses are bigger than the Atlantic walruses.
These walruses are carnivores and prey on birds, mammals, aquatic crustaceans, marine invertebrates. The International Union for Conservation of Nature has listed the species of walrus in the Vulnerable category while the status of Laptev walrus is listed as Data Deficient. The population of walruses is highly affected by hunting and predation.

Commercial harvesting is highly affecting the population, there are more than 200,000 Pacific walruses and 20,000 Atlantic walruses at the moment. Studies suggest that the worldwide walrus population would be around 250,000.
Where does a Laptev walrus live?
The subspecies of walruses (Odobenus rosmarus) are distributed in the Arctic Oceans and subarctic seas of the Northern Hemisphere. The Laptev walruses are found in the Laptev Sea, while the Pacific walruses inhabit the Bering Sea and in the warmer months, they travel to the Beaufort Sea and the East Siberian Sea.
The Atlantic walruses dwell in the eastern and western Atlantic Oceans.
What is a Laptev walrus's habitat?
While talking about the Laptev walrus habitat, these animals generally dwell in the areas of the Arctic Ocean, they prefer shallow waters where food is easily accessible. Most of their time is spent either in or around water.
Male walruses are generally found on sand or boulder beaches, while female walruses spend their time on ice. These animals usually migrate south during the winter and north in the summer season. Migration is dependent on the presence of ice.

Also, these animals are prone to tusk infection that could reduce the usual lifespan, hunting, and poaching also lowers the lifespan of these beautiful animals.
How do they reproduce?
These animals follow the polygynous mating system that means males mate with multiple females in each mating season, they generally mate between January and April. Walruses turn sexually mature when at the age of five to seven but mate after 15 years of age.

The gestation period generally lasts for around is 15 months and females generally give birth to a single calf or offspring. The average weight of the calf is around 132 lb (60 kg).
The female Laptev walruses are best known for their care towards their offspring. The calves usually live with the female herds for a few years as it helps to prevent predation.
At the age of two, they learn the skills of scavenging and at three, they are completely weaned. Males are not involved in any kind of parental care.
What is their conservation status?
The International Union for Conservation of Nature has listed the species of walrus in the Vulnerable category while the status of Laptev walrus is listed as Data Deficient. Walruses found in Svalbard and the Russian Atlantic are protected under the North Atlantic Marine Mammal Commission.
Also, the species is listed in Appendix III of the Convention on International Trade in Endangered Species. The Laptev population would only be around 20,000 as of now.
Humans often hunt walruses for their skins, bones, and tusks. Global warming has also emerged as a major threat for walruses over the years.
