Document Summary

Is it a myth that camels humps are filled with water. Yes it is a myth, the humps are jam packed with fat, 80 lbs of compacted fat. The camel hump consists of a giant mound of fat. The hump can weight up to 80 lbs. Allows the animal to survive a long time (up to 2 weeks) with limited food. Camels do not store water, they store the fat tristearin c57 h110 o6. This fat is also a source of water. When it is metabolized allowing for camels to undergo long periods without drinking. They do not get water directly but get it through metabolizing. Not a source of food, but rather nutrients. Camels can endure long periods without water because: They have an extreme tolerance to water loss (up to 30-40% of their body weight) They can minimize water losses (i. e considering water in the nostrils) The long nose is good at saving water.
