Aim/Hypothesis: To compare the anatomy of the cane toad and the rat in order to find the differences of two different animals and how the animal has changed throughout time to suit its living conditions.…
There are many different types of invasive species in Florida. There are a variety of birds, mammals, reptiles, and amphibians that live in Florida. For an example of an invasive nonnative bird that lives in Florida is the Turquoise - fronted Parrot. The Turquoise - fronted Parrot is known to live in four counties for at least ten years. Also, there is a variety of amphibians that inhabit Florida, such as the Cane Toad. The Cane Toad is a nonnative invasive amphibian that is so large that it is known as the Giant or Marine Toad. The Cane Toad has been known to live in Florida since the 1930s. Another nonnative invasive species that belongs to the reptile class is the Spectacled Caiman Crocodile. The Spectacled Caiman Crocodile was first discovered…
The toads would spend more time in the water. Therefore the toads would mate in the water, but it didn’t work out so well the first time. However, the male toads began to grow rough pads on their legs and fast. It took only two generations for the toads to adapt.…
Hypothesis : From my research and observations, I think animals are the reason why the pond water is dropping.…
The three main traits that differ between the frogs are the spots on their body, the color of the eyes and the color of the skin.…
Frogs are predicted to be most active in warm climates because blood functions slowdown in cold environments. This is true because you can freeze a frog for many years and then defrost them back to life. Also that is why frogs in warmer areas are more active than frogs in colder areas such as the wood frogs. Wood frogs cannot move during the cold weather because their body freezes down and so the frogs in the warmer areas can be active all…
During the early and mid twentieth century up until the mid to late nineteen seventies, the Cuban Tree frog seemed to be of no harm to American soil. However, throughout the…

The cane toads caused catastrophic damage to the environment. Almost all animals that ate the cane toad died; as a result, there was a 95% mortality rate. Worst of all, cane toads move at alarming rates. Originally they moved six miles annually, but today it is anywhere from twenty-five to thirty-five (Guarino [2-4]). Cane toads are a threat to the environment and all wildlife.…

I was amazed to find out just how ancient frogs are. For 190 million years, the ancestors of modern frogs have roamed the earth, looking much the same as they do today. This means that at one time when there was a huge dinosaur eating a plant, there could have been some type of frog down by its feet. About 3,800 species of frogs and toads have developed since the dinosaur days. The secret to their success is their amazing adaptability. Frogs have evolved to live in a large variety of climates. They can be found just about anywhere there is fresh water- on all continents except Antarctica. Though they thrive in warm, moist tropical climates, frogs also live in deserts and high on 15,000-foot mountain slopes.…
Adult Cane Toads are active at night during the warm months of the year. They tend to seek shelter during cold or dry weather; they can survive the loss of up to 50% of their body water and temperatures ranging from 5-40 degrees Celsius. They are highly adaptable to a range of environmental and climatic conditions which is the reasons for their fast expansion, they now inhabit most of Australia’s tropics and sub-tropics and have reached now Western Australia…
The California red- legged frog (Rana draytonii) was the threatened species and was found in the western United States. More than seventy percent of California red- legged frogs have been eliminated from their former extent. Nowadays, this breed is still popular in the Bay area but isn’t much like before (USFWS 2002).…
Frogs and other amphibians are important for several reasons. One reason is that they are an integral part of the food chain, as they serve as both predator and prey (What Do Frogs). Without them, the ecosystems they live in would suffer. For example, frogs feed on pests, such as mice or insects, which infest human homes and consume crops. Without frogs and toads to feed on them, the populations of such pests would grow rapidly. Many of their prey even spread diseases, like mosquitos which spread malaria, so frogs play a direct role in keeping humans healthy. Tadpoles, juvenile frogs and toads, clean waterways by feeding on algae, which cuts down on costs that would otherwise be needed for water filtration (Why We Must). Additionally, frogs also serve as prey for a variety of organisms, from predatory birds, fish, and snakes, to larger insects, other frogs, humans, and more. If frogs die out, all of their predators would have to cope with a lack of food sources as well (What Do Frogs). Furthermore, because amphibians live in both water and land, they play key roles in transferring nutrients between the two. Without them, all organisms in their environments would suffer. Food webs such as this are simply too interconnected for the loss of one creature not to affect the rest, especially not creatures as vital as amphibians (Amphibian…
Frogs vary in different shapes, sizes, colors, and textures. They have smooth, moist skin, long stripy legs, and are likely to be found in damp habitats in a garden or somewhere in or out of water. They have a narrow body, bulgier eyes, and long hind legs which allows them to jump high. Frogs have many different eye colors such as brown, green, red, gold, and silver along with different shapes and sizes of their pupil. Some frogs have very sticky padding on their feet while others have webbed feet. Frogs also lay their eggs in clusters, as opposed to toads which lay their eggs in long chains.…
