8 Amazing Facts About Walruses!
Walruses are fascinating, large marine mammals known for their distinctive tusks and intriguing social behaviour. They are found in the Arctic regions and are well-adapted to live in cold environments.
1. Tusks for Multiple Uses:
Both male and female walruses have long tusks, which are actually their elongated pointed teeth. These tusks can grow up to 3 feet long and can serve various purposes. Walruses use their tusks to break through ice for breathing. They use them as a defense against predators like polar bears and orcas. Larger tusks often indicate higher social status within the herd.
2. Adaptations for Cold:
Walruses are highly social animals and often gather in large groups called herds. These herds can consist of hundreds or even thousands of individuals. Walruses are well-adapted to cold Arctic environments. They have a thick layer of blubber, that insulates their bodies against the frigid temperatures of their icy habitat. This blubber also helps them stay buoyant in the water.
3. Incredible Diving Abilities:
Walruses can dive up to 300 feet (90 meters) deep and stay underwater for about 30 minutes.They dive to forage for food like clams, snails, and other organisms on the sea floor.
4. Sensitive Whiskers and Large Body Size:
Walruses have hundreds of sensitive whiskers around their mouth. They help them detect and identify food on the ocean floor, even in complete darkness. Adult male walruses weigh 1,800 to 3,700 pounds and measure up to 12 feet long. Female walruses are slightly smaller.
5. Unique Color Changes:
The skin of a walrus is incredibly thick, especially around the neck and shoulders, which protects them from predators and harsh climatic conditions. Walruses are typically greyish-brown in colour but can appear pink or reddish when they are warm due to increased blood flow to the skin's surface.
6. Diet:
Walruses primarily eat invertebrates like clams, worms, and snails, but also consume fish and occasionally seal carcasses.They use their powerful lips to create suction, pulling prey out of shells. Their whiskers help locate food on the ocean floor with great precision. Walruses depend on sea ice for resting, breeding and feeding. Climate change and melting ice reduce habitat and food availability.
7. Protective Parenting:
Mother walruses are protective and nurturing, carrying calves on their backs or keeping them close while swimming. Calves are typically weaned after two years, learning survival skills from their mothers.
8. Lifespan and Growth:
Walruses can live up to 40 years in the wild. Lifespan is influenced by predation, environmental conditions, and human activities like hunting and habitat disturbance. It serves as an energy reserve during food scarcity or migrations.
