Transcript of Camel Adaptations
Camels being from the genus Camelus are large endothermic mammals that split into two species the Dromedary camel (Arabian) and the Bactrian Camel (central Asia)
The average camel lives for approximately 40-50 years and weighs approximately 300-1000 kilograms (Dromedary Camel) .
Camels are well known for being very well adapted to extremely hot habitats and have many physiological, behavioral and structural adaptations to help it reach homeostasis
Physiological Adaptations (water)
The urine concentration of a camel is greater than sea water making it able retaining more water. Having concentrated salt level in the urine allows the camel to drink salty waters, eat plants that contain a high concentration of salt
Its loop of Henle is large to retain as much water as possible from the kidneys. 7.89 in comparison to the value of 8.5 in kangaroo rats. Showing camels are effective producers of concentrated urine.
A camel is able to consume a third of its body weight in drinking 200L of litres of water in 3 minutes. The erythrocytes of the camel are oval shaped which resist osmotic variation without rupturing; being able to swell to 2x their size
Being endothermic camels are able to fluctuate their temperature 6-7C. The camel can tolerate the high temperatures, and stores the heat during the day which causes drastic body temperature fluctuations. the camel stores the heat until the night allows for the stored heat in the camel to be released the camel has not wasted any water during the day. it gains approximately 2900 kcal of heat which corresponds with about 5 liters of water being saved.
Physiological adaptations (temperature)
The camels low surface to volume ratio allows the camel to reduce the amount of heat loss to its surroundings as it does not have to have a high metabolic rate compared to smaller animals
The hump of a camel contain what?
The camel has a similar heat barrier with its coat of fur. The thick fur of the camel can significantly reduce the amount of environmental heat gained as it creates an insulation layer.
It only has two toes with a very large surface area which is perfect for sand. The foot has a large calluses over 1cm thick. All the surfaces that come in contact with calluses to keep the camels skin from being burned by the hot sand
Camels have learned to face the sun while lying down, causing less of the body exposed. In this way the body catches less sun and doesn’t heat up at fast.
Camels urinate on their legs to try and cool down the blood passing through their legs.
They spend their nights searching for food as it is cooler are will reduce energy loss and water loss
