Document Summary

Have a ~80 lbs hump of fat. Allows them to survive up to 2 weeks with limited food. Camels store tristearin fat (c57h110o6) that"s has a lot of potential energy. The fat is also a source of water (c57h110o6 +163 o2 114 c o2 + 110 h2 o) allowing them to go without water for long periods if needed (usually not used for water production) Minimize water loss by condensing water in nostrils: nostrils are cool, warm air is expelled from lungs allowing water particles to condense in nostrils when the air passes through. Preparing for flight eat in spring and summer (can eat up to 12 hrs. a day and even more before and after they fly (winter)) By eating they are stock piling fat reserves. Geese practice flights to prepare for the metabolic stress in winter. While flying to destination they tap into their fat reserves geese can lose half of their body weight during migration.
