Mammals are relatively complex and intelligent animals.

They give birth to live offspring, have hair or fur on their bodies, and possess mammary glands that produce milk for their young. They breath air with lungs and have ears that stick out instead of the earholes, such as what reptiles and birds have.

Walrus often dive for 5 to 8 minutes because their red blood cells (that carry the oxygen) are exceptionally large. In addition, they have lots of myoglobin in their muscles that can store oxygen.

Why do Walrus have high blood circulation?

  • The walrus can remain under the surface of the water for up to 10 minutes.
  • They will usually surface every 5 to 8 minutes to get air and stay at the surface for about 1 minute.
  • They will stay in the shallow waters, no more than 262 feet below the surface.
  • When they dive the blood flow is cut off from their skin, extremities, and stomach. All of these adaptations allow for efficient and lengthy use of oxygen stores.
  • They have a larger percentage of blood in their bodies to carry oxygen, about 12 percent of their weight as compared to only 7 percent for humans.
