There was a time in history when the oceans were overly polluted with trash of various sorts. The water was so polluted and the food source for the ocean life was diminishing. This was the habitat of the blowfish. Their food became so scarce they began to eat the very things that were polluting the waters. The blowfish began to mutate with what they were eating. The Bottle Blowfish came to be from a mutation between a plastic bottle and its consumer, the blowfish.…

Was it right that the Michigan Department of Natural Resources cut Chinook Salmon stockings by almost 70% in Lake Michigan?…
The Red Cedar River is home to many interesting and unique species of organisms, including crayfish. Crayfish play a significant role in the ecosystem by serving as a food source to different organisms. By studying the factors that influence the amount of crayfish in a freshwater environment, researchers can discover more about how ecosystems persist. The overpopulation of crayfish in freshwater systems can lead to various negative impacts, such as the feeding on plants that are major food sources for different aquatic organisms and the eating of fish eggs leading to the decrease in population sizes. If there is evidence proving a positive correlation between phosphorus concentration, a chemical element that can enter water through waste or…
In America there is a number of invasive species but the one I chose the Brown trout. The Brown trout is a european species of the salmonid fish family. The Brown Trout’s scientific name is Salmo trutta. It was introduced in the mid 1800’s to america. The reason why the Brown trout is an invasive is because the Brown trout competes with other native species of fish(and obviously wins) and in some cases end up breeding with them. This has conservationist worried about the genetic makeup of the native species.…
Blue-tongue Lizards are found throughout most of Australia. Blue-tongues usually live in open country with lots of cover such as tall grasses, litter and low shrubs. They shelter at night among these covers, in burrows and under large objects on the ground such as rocks and logs.…
Upper East: This stream had a higher population of guppies with a varied amount of male and female. There is still a high proportion of bright spotted males however these males are not as bright as in the upper west. There are no predators in this stream and an adequate amount of food. The water quality is a grey brown on the program.…
This fish tends to be found in the northern, colder climates. They can grow much larger than the largemouth bass. The walleye is a much more picky eater than the bass. The walleye will only eat at a certain depth depending on the water clarity, and temperature. It is very popular to catch these fish while ice fishing. In the winter time the walleye becomes less picky and will key in on much more fish, making them easier to catch. When ice fishing you must have a safe thickness of the ice. Then you must drill a hole through it with a device called an ice auger. Then you use tiny rods that average at around 28 inches to pull these walleye out of the water. If you are looking for a little more of a challenge, the walleye may be just the fish for you.…
In the Pacific Northwest, salmon are an incredibly important part of the ecosystem. Their presence indicates the health of rivers and there are over 100 species that depend on salmon as a source of food (Rahr). As salmon move from saltwater systems into freshwater systems again, they bring essential nutrients with them. These nutrients are put back into the ecosystem when the salmon are consumed and when their bodies start to decompose. Many of these nutrients even make their way back into the forest when bears drag the bodies of their prey away from the river (Rahr). The cycling of nutrients is essential when it comes to the health of forests and rivers. Besides improving the overall health of the ecosystems that they are a part of, salmon…
“The common Guppy, is also known as the millionfish, mosquito fish, or rainbow fish by tropical fish keeping enthusiasts. They are a highly adaptable species that can survive and even thrive in environments that many other tropical fish species would be unable to tolerate.” (The “Un” Common Guppy) The guppy is one of the world’s most widely distributed tropical fish, and one of the fish that is most commonly chosen first to be taken home from the store. It is a freshwater aquarium species. Guppies were originally found in northeast South America, and now they are found all around the world.…

One of the most memorable books of my childhood is called “The Rainbow Fish”. In kindergarten, we read this book almost every day. I don’t know why I liked this particular book so much. Was it the colorful pattern the book cover had? I just don’t know. I thought this book was the most amazing book I ever heard of. When I think of this book, I think about how my teacher helped me and my classmates learn how to read better with this book. My literacy experience started at home. Every one can’t say the same. Sitting in bed every night, waiting on my mother to come tuck me in and read me a bedtime stories. When she finally came, she would walk towards my bookshelf to grab a particular book every night. I never knew what it was called, but I know…

Guppies (Poecilia reticulata) are fish that are accustomed to warm water habitats that derive from the native fresh water streams and rivers in Trinidad (Magurran 2001 et al. Philip 2001). As the environment changes this will act as a key factor to shaping the behavior of the guppies, which will play an important role in mating and building courtship. Courtship by males encourages female receptivity, which will increase their chances of interaction (Farr, 1980). The behavior of the guppies is dependent upon the guppy’s response to the internal and external stimuli within their new environment. When animals experience a sudden change in environmental conditions they require time in order to adjust to their new habitat. In regards to determine the change of environmental conditions based on temperature, an experiment was conducted to test the hypothesis of interaction during this temporal change: by determining the temperature of water the female guppies will interact with males guppies. This experiment will consist of two treatments: warm water at 24 degrees Celsius and room temperature water at 20 degrees Celsius.…
The volcanic islands known as the Galapagos Islands are found 600 miles off the coast of Ecuador and are home to the Galapagos penguins, the only species of penguins in the world to live north of the equator. Despite the common belief that penguins only live in the Arctic, the Galapagos Islands have temperatures that vary from 70-90º Fahrenheit over the course of the year. The distribution of these birds in their environment correlates with the “Cromwell Current, which provides cold nutrient-rich surface water,” meaning that the penguins follow the cool water patterns (Davis). The penguins feed on small fish like sardines and mullet, and their predators include sharks, sea lions, hawks, and crabs. The Galapagos penguins have been adapting for…
