Chameleon Chamaeleonidae is the scientific name given to them and Chameleon is their common (Vitt, 2014, Para. 1). Most researchers suggest that chameleons originated from a small country beside Africa called Madagascar. For this reason that deep forest of Madagascar is where most of the chameleon species are found. Additionally, forests on the main land of Africa, southern Spain, southern Asia and the Middle East also have different other species of Chameleon (Means, 2013, 372). They are later found in some other countries of the world. Chameleons have very interesting Characteristics and some are so complicated. What if an animal can change its own skin color to whatever color of its surroundings, sat there as if it is invisible, the eyes can focus on two total different direction at the same moment and stick out its tongue twice its own length for any prey that passes by. Why not consider what the animal is. There is no other animal that has amazing characteristic of the smallest Reptile Chameleon. Furthermore the essay describes what chameleons look like? The best chameleon’s habitat and their breeding cycle? And some of the characteristics Chameleons enlightens.
Chameleons are the smallest type of reptile. They don’t move that fast but much more attractive when displaying their beautiful colors. Different chameleon species have different sizes. Their maximum adult growth length is ten to sixty five centimeters long (sur or titl, date, para. 1 ). Distinguishing between male and female are sometimes recognize by their colors, the size of tail base and most likely their body size. Both their body sides are flat but male Chamele...

All in all, Chameleons are highly numbered in the forests of Madagascar than any other countries of the world. But it are migrating to most tropical countries of the world. Interesting species are forming with new different color changing abilities and sizes. They may not have that speed as some of the fast moving reptiles, but still have the capability to defend themselves from predators and multiply. Chameleon’s survival depends on their unique characteristics. Example the clever way of hiding they do by changing their color to the colors of their surroundings, seeing every movement happening around them while waiting for their prey to pass and their tongue slipping out their mouth in sudden speed for the prey. This unique characteristic shifts the limits of Chameleons survival.
Calyptorhynchus banksii, or red-tailed black-cockatoo, has coped with extreme variations in its environment. Much like the plant species of Australia, the red-tailed black-cockatoo has evolved physiological and anatomical adaptations that have allowed it to survive in changing surroundings. One of the most prevalent adaptations was that seen in the beak apparatus. Changes in the beak allowed the cockatoos to consume the newly evolved sources of food. The metabolic requirements of the cockatoos and the availability of food are also forces that have influenced the beak apparatus and the distribution of red-tailed black-cockatoos throughout Australia.
Similarly, as arboreals, Veiled chameleons mainly reside in trees. The body design of these chameleons
Chapter two consists of Darwin continuing his studies. He talks about variation in the natural world compared to the domesticated species. He defines species variation and says that every naturalist has a different idea of the definition. He explains to the reader that linking other species together by characteristics of variation is challenging because some are so similar but vary in other ways. Environmental conditions could be effecting the variation. Climate, temperature, the separation of the animals could transform them. The species changes over time and have chi...

Throughout time, one theory has remained constant in terms of why giraffes developed longer necks. The idea, which was presented by Charles Darwin states quite simply that giraffes selected for longer necks in order to reach the food that was higher off the ground during the dry season. No one has ever challenged that idea until 1996. Initially, Gould argued that "the story-the giraffe evolved its long neck in competition to reach scare foliage-is supported by no evidence" (18). That's when two scientists, Robert Simmons and Lou Scheepers made the claim that necks evolved for a very different reason: sexual selection. Within this paper, information will be presented that argues both for and against the theories made by Darwin and Simmons and Scheepers.
Although the four anole ecomorphs are almost identical in appearance and inhabit the four islands, they are not closely related. The lizards on each island descended all from a few original species that later evolved and differentiated into a large number of descendants. It can be observed that in all four species, their ancestral lineages have evolved independently but evolving the same traits for the habitat they were in. Harmon explains how this can show the predictability of evolution on a longer time
Flight is the main means of locomotion for many species of birds. To understand how ratites evolved to losing their ability to fly, one must understand the evolution of flight. The changes in the environment allows a species to occupy the formerly empty ecologic niche as a new, improved opportunity for living (Dobzhansky 1973). Once the threat of predation disappeared, ratites were able to utilize the new ground niche to strengthen their ability to run, which provided an alternate way to escape predators. This study of evolution shows the importance of adaptations flightless birds have had to undergo to meet their needs of survival.
...n in the examples above that some animals prefer to build a toxic chemical and to advertise it to their surroundings for protection, while others rather not do so. Other animals rather build the ability to blend in the surrounding as a protection key in different ways. Some blending mechanisms result in changing of coloration of having a color similar to your native habitat in exchange for toxicity. On the other hand animals use the ability to produce poison or the ability to blend in to hunt as well. The B.schlegelii uses its poison to hunt and immobilize its prey. Yet it uses bright colors to advertise itself from other potential predators. Furthermore, there are animals that use hiding abilities to hunt. Overall, we see different examples in 3 different related classes, the reptiles, amphibians and mammals of usage of coloration and it relationship with toxicity.
In this research paper I will be discussing the Yellow-Bellied Three-Toed Skink and how instead of this reptile laying eggs like most reptiles would do, it is giving birth to live young instead. The Yellow-Bellied Three-Toed skink (Saiphos equalis) is a small reptile in size that closely resembles that of a snake, but with four legs. This specific species of skink can be found in New South Wales, Australia. It has been discovered that in the cold regions of New South Wales this organism is producing live young. However in the warmer regions of New South Wales this same exact species is laying eggs. (Handwerk, 2010). As stated in the National Geographic News, “Evolutionary records shows that nearly a hundred reptile lineages have
The Komodo Dragon is a large species of lizard that is only found on a handful of islands in the Indonesian archipelago. Not known to the world until the First World War, the Komodo Dragon is actually a species of Monitor Lizard that has been evolving in island isolation for millions years, which has led to it becoming very large indeed. The Komodo Dragon is not only the largest lizard in the world, but it also one of the most aggressive and is so powerful that it is able to take prey many times it's own size. However, Komodo Dragons are also in severe danger in their natural environments as hunting and habitat loss, along with a shortage of prey, has led to population declines on the few islands where
Even though there are so many differences between reptile species, there are a few things they all have in common. All reptiles are coldblooded, which is not quite right because there blood isn't cold. Coldblooded or poikilothermic actually means that the animals temperature must be regulated by external factors, that is why lizards are always sun bathing to get warm or in holes to cool off.
Hyla versicolor, commonly know as the Gray Tree Frog or the Eastern Gray Tree Frog, is an amphibian that is referred to as the “Chameleon of the Frog world” (Craighead, 2004, p.1) because of its ability to change colors. “This frog was once thought to be the same species as the Cope’s Gray Tree Frog”. They can only be distinguished by their calls and the fact that the Cope Gray Tree Frog is diploid while the Gray Tree Frog is tetraploid (NPWRC, 2004). The Gray Tree Frog is classified as follows:
The similarities and differences between the dog and the lizards’ digestive and reproductive systems are explored within this essay.

Throughout the various phyla discussed evolutionary advancements are relevant. Starting from the basic, simplistic life forms of a sponge, up to the intelligence of an octopus and advance organ systems of Annelida the changes have only improved. Some species changed and evolved because as populations grow, they spread out farther and different conditions begin to affect their life. Why some species haven’t changed is because their body plan and system works for the environment they inhabit. Evolution has helped animals spread out all over the world and adapt to various conditions, seen in the habitats Aschelminthes can prosper in.
