What adaptations does a camel have to survive in its environment?
Camels have a number of adaptations which help them survive in their desert environment.
- The most obvious is that camels have a hump (or two if they are bactrian camels) which stores fat, which metabolises for energy. This enables the camel to go without food and water for a long period of time. The hump does not store water.
- When they do access water, they can drink up to 46 litres of water in one session.
- Camels have two rows of long eyelashes to help protect them against the desert sand.
- They can close their nostrils, also for the purpose of keeping out sand.
- They also have hair lining the inside of their ears to protect their ears from the sand.
- Their legs are long and strong, and their feet are split hooves with broad pads which splay out over the desert sand for more stability, preventing them from sinking into the sand.
- Their thick, leathery knees do not get burnt by the hot sand when they kneel.
- Camels have thick fur and underwool which acts as insulation against both the hot desert days and the cold nights.
- Camels' lips are thick and leathery, which enables them to eat prickly desert plants without it hurting their mouths.
- A camel's internal temperature can fluctuate with the conditions - this is an advantage because it helps the camel conserve water by not sweating as the external temperature increases.
- Camels absorb water in their blood, and their erythocytes (a type of blood cell) swell to almost 240% than their normal size without bursting.
- A camel's kidneys can concentrate urine to reduce water loss; in turn their urine will become very syrupy and thick and be extremely salty.
- The colour of their bodies helps them to blend into their environment.
Koalas already have everything the need to survive. They are equipped with numerous adaptations that enable them to survive, and tribe, in their habitat. Refer to the related question below for these adaptations. However, few animals as able to survive man's interference in their environment. The koala is no exception. If man continues to degrade the koala's environment, koalas are unlikely to survive.
Adaptations are genetic mutations, which increase a populations ability to survive and reproduce in its environment. Natural selection is the process in which the populations that are best able to survive in their environment are "selected". Such "selections" result in the removal of populations that are unfit in their environment, in favor of the populations that are fit.
Each organism has adaptations for its specific environment. Those adaptations will allow it to survive easily in one environment, but may make it impossible for that organism to survive in another environment. For example, a polar bear can live in the Arctic, but it would die of heat stroke within hours if you took it the Sahara Desert. Because each environment supports different adaptations, different organisms live in each environment, and each environment adds to…
