Their body shape and physiology has adapted to suit the harsh environment. Over thousands and thousands of years, the environment has put extreme selection pressures on camels, and they have adapted accordingly to the animal that we see today.
00:00:05,350 -- 00:00:09,379
camels are very well adapted to live in
00:00:07,580 -- 00:00:12,200
the desert which is hot and dry during
00:00:09,379 -- 00:00:13,850
the day but cold at night. They have
00:00:12,200 --00:00:15,920
adapted thick fur on the top of their
00:00:13,850 -- 00:00:19,070
body for shade but thin fur everywhere
00:00:15,920 -- 00:00:21,680
else to maximize heat loss. A large
00:00:19,070 -- 00:00:23,540
surface area to volume ratio also helps
00:00:21,680 -- 00:00:26,450
to keep them cool because he has more
00:00:23,540 -- 00:00:28,280
places to escape from but camels have
00:00:26,450 -- 00:00:31,760
adapted to tolerate body temperatures of
00:00:28,280 -- 00:00:33,140
up to 42 degrees Celsius. It's actually a
00:00:31,760 -- 00:00:35,120
myth that camels can store water in
00:00:33,140 -- 00:00:36,739
their humps but they can go for a very
00:00:35,120 -- 00:00:39,199
long time without drinking water and
00:00:36,739 -- 00:00:42,379
they can drink up to 46 liters in one
00:00:39,199 -- 00:00:44,479
session. They lose very little water
00:00:42,379 -- 00:00:45,769
through perspiration because their body
00:00:44,479 --00:00:48,649
temperature changes throughout the day
00:00:45,769 -- 00:00:49,909
so there is no need to perspire. They
00:00:48,649 -- 00:00:51,469
also leave very little through
00:00:49,909 -- 00:00:54,559
urination because their kidneys
00:00:51,469 -- 00:00:56,690
concentrate urine. Their hump is actually
00:00:54,559 -- 00:00:58,850
faster which can be respited to release
00:00:56,690 -- 00:01:02,359
water and this allows them to go a long
00:00:58,850 -- 00:01:03,949
time without food which is scarce. Camels
00:01:02,359 -- 00:01:05,540
have adapted to have very large flat
00:01:03,949 -- 00:01:07,909
feet to spread their weight on the sand
00:01:05,540 -- 00:01:10,579
and skin between their toes helps to
00:01:07,909 -- 00:01:12,649
stop them sinking they also have two
00:01:10,579 -- 00:01:14,149
sets of eyelashes and large slit light
00:01:12,649 -- 00:01:16,509
nostrils to keep the sand away from
00:01:14,149 -- 00:01:16,509
their face.
