My Favorite Organism: Giraffe
Transcript of My Favorite Organism: Giraffe
Food Adaptations Giraffe have adapted to have superior size and weight. The average weigh of a giraffe is about 2800 lbs. The average height of a giraffe to the height of 5.75 meters feet. This size and weight of the Giraffe prevents them from having lots of predators. The Giraffe eat around 140 lbs of fresh vegetation per day much of this vegetation is thorny. To process these thorny foods the giraffes have evolved first a very strong tongue. There tongue has evolved a tongue that is the strongest in mammals. The tongue is also very long as well which is the average of 35 centimeters . Giraffe mate when the female giraffe go into estrus which is also known as heat. The female to allow the male to know that he is it heat has evolved the ability to release pheromones that let the male giraffes know she is in heat. The Hooves of a Cow and the Hooves of a Giraffe. An organism with homologous structures to a giraffe
is in fact humans. The number of bones in a human's neck and a giraffe neck are the same. The only living relative of the giraffe is the Okapi Fossil of the Helladotherium I picked the Giraffe for this assignment for two reasons. The first reason being that I wanted to pick an animal from the continent of Africa. It is my belief that the animals from Africa are some of the most wild and documented animals in all of the Earth. Out of all the animals in Africa the giraffe adaptations are the most prominent and easy to recognize. It may appear as if a Giraffe's don't move fast speed. Mostly likely due to their height of their legs and neck. However Giraffes have evolved the ability to gallop at 31-37 miles an hour. Although that is not as great as the average speed of a lion 50 miles per hour it still allows them the chance to escape. Besides a giraffe's neck one of the most noticeable features of a giraffe is their spots . These coloration is very useful in avoiding predators due to the camouflage it provides. The giraffes protection against lions is there hooves. The adaptations of their hard hooves can allow them to provide a lethal kick to lions. The Giraffes have evolved very good eyesight. Although this is very important in spotting predators it is also very important in finding food as well. The Giraffes has evolved the ability to survive for two weeks for out water. Allowing them to find food even in times of drought. The most prominent adaptation of a giraffe its neck allows it to reach leaves that other herbivores cannot reach. Why this Adaptations might have arose. The adaptation I have chosen for this section is the ability to go two weeks without water. That adaptation arose because of drought. A long time ago some form of giraffe did not have the ability to survive without water for very long. Due to variation some giraffe gained this ability and other did not. The giraffes that very able to survive for two weeks without water survive while the giraffes that didn't died off. Eventually only leaving the giraffe with this ability. The Paleotraginae and Helladotheriumn are also relatives of the giraffe however they are extinct. Bibliography http://www.ehow.com/about_6326336_giraffe-adaptation.html
http://www.theanimalspot.com/giraffe.htm To help protect a Giraffe from bacteria the giraffe have evolved bacteria that is anti-septic. This prevents the giraffe from being too selective in food choice. Allowing them to find more food. Changes in the environment that would have impact the success of your organism If there had been an increase in the natural predator of the giraffe then the biological fitness of the giraffe would have most definitely decreased. If there had been increase
in the hunting of giraffe
by humans then the biological
fitness of the giraffe would
have most definitely increased.
