Introduction
The Saltwater Crocodile and the Fresh Water crocodile are highly recognised species in Australia. The Saltwater Crocodile is scientifically known as the Crocodylus Porosus (C.porosus) and the Fresh water crocodile is scientifically known as the Crocodylus Johnstoni (C.johnstoni). Both of these creatures have had to adapt to the variety and change of climates that Australia has. The similarities and differences of these adaptations will be discussed, along with a prediction of which species is more likely to survive within Australia.
Summary of Adaptations
The following is a summary of adaptations of the C.porosus and the C.johnstoni. Each adaptation has been classified as structural, behavioural or functional. Each of these adaptations will be discussed further in depth as a similarity or difference between the two animals.
Similarities
The C.porosus and C.johnstoni have various similarities within their structural, functional and behavioural adaptations. One of these similarities is their dietary needs. Both types of crocodiles are carnivorous and feed on a wide range of food including; insects, fish, amphibians, reptiles and mammals. Although, the size of the prey the crocodiles are eating differs. C.porosus, being the larger crocodile generally eats larger animals such as wallabies and wild bores. C.johnstoni eats smaller animals. This leads to the structural adaptation of how they eat their food. The C.porosus has blunt teeth but an extremely powerful jaw to bite down on its prey with ease. The C.johnstoni has many sharp teeth to aid in catching and eating its prey.
Another similar adaptation the C.porosus and C.johnstoni share is their habitat. Both of these crocodiles are found throughout northern Australi...

In the lab the isopods were observed in a way to where behavior and structures could be properly recorded. The isopods were revealed to two dissimilar scenarios, normal temperature water vs. warm temperature water, to calculate which environment was most preferred. In each distinct scenario ten isopods were placed ten a choice chamber, one side being normal temperature (26.7celsius) and the other being warm temperature (43.3 celsius) , and observed for a total of ten minutes with thirty second intervals which was when we recorded our observations. After observations, it was seen that normal conditions was the most preferred environment by the isopods. In the scenario the Isopods exhibited taxis behavior, which is behavior caused by factors such as light, temperature, water and such. Nothing physical, but rather environmental.
I believe that the Semibalanus will inhabit the open area of the rock and out compete the Chthamalus for the open area. I think this because the Semibalanus species seems to be the better competitor of the two.
Outline the physical similarities between the (Blaptica dubia) cockroach and the cricket. Explain previous studies on physical stress in the cricket and in different species of cockroaches. Briefly discuss how the metabolic rate between the two species has been found to be very similar.

Now, Darwin was not the first to land on this group of islands, but rather was the first to document an extensive analysis on everything from animals, plants, habitat, and climate. The majesty held by the landscape described by Darwin is unparalleled by no other known to human kind, even today.“Imps of Darkness” that emerge from the depths of the sea, giant tortoises whose size are incomparable to any European tortoise and specimen of finches indigenous to its own respective island are examples of Charles Darwin’s analysis upon his first encounter with the archipelago, Galápagos. Countless years have passed since those fateful days Darwin resided in the Galápagos, but was Darwin accurate in his depiction? How much has changed since then? What new discoveries have been made upon Darwin's analytical visit?

Darwin’s observations from the islands made him want to come up with some explanation to why this occurred. He began to do research of each the species that had lived on these islands and observe all of the characteristics that had. He noticed that the islands h...
When comparing terrestrial fauna found in Bolonia and the glacial valley of Glendalough, many differences were noted. This portion of the trip was carried out in the matorall in Bolonia, which is a biome that occurs in midlatitude coastal regions (Campbell, 2011). ...
