Fish Adaptation and Physiology Kim Rosnik SCI/230 10/21/12 Kelley Gaske Fish Adaptation and Physiology In our modern day world, we have many organisms that live in two main areas. The first main area is on land, and the second is in water. The organisms that live in water are very different then the ones that live on land. Even though land and water animals need the same necessities to survive, they have adapted in different ways. This paper is intended to describe the physiology of fish and how they have evolved in their environment of water.
I also chose to research oceanography because most of earth is made of water. Oceanography also relates to me and and society. We use things from the ocean in our everyday life. Scientists use fish oils for medications and vitamins. Also things in the ocean can be used as food.
Marine Ecology Lab #1: Phytoplankton and Zooplankton of South Bar Question (1): How would you describe the color of the water? Why is the color of the water in the Sydney Harbor, and the NW Atlantic in general, different from the color of seawater in the tropics? Tropical seawater is relatively clear and colorless, while temperate seawater is green in color and over a thousand specks moving within. Tropical waters are characterized by nutrient poor and high light water. The murkiness of the temperate waters is due to high productivity of plankton.
These gases, along with several others, remain within the atmosphere because of the greenhouse effect. Carbon Dioxide, much like water, goes through a cycle referred to as the carbon cycle. Through this cycle carbon is exchanged through the Earth’s atmosphere, biosphere, ecosphere, geosphere and lastly the hydrosphere. Because of this cycle the carbon dioxide flowing in the atmosphere will eventually be absorb into the ocean. There are different ways it can end up in the ocean, for example, through rain fall or even rivers.
Examples of such environmental factors include light intensity, temperature, and distance from a light source(1). Elodea condensers, also known as American water weed, is a common, aquatic plant in North American lake ecosystems. It provides both food and habitat for many aquatic life forms. Elodea can grow in a wide range of conditions, including various depths of water and in various sediment types (2). In addition to its ecological importance, Elodea is commonly sold as an aquarium plant.
Water flowing westwards is warm, 28ºC in the western Pacific whereas the water off the coast of South America is cold, 20ºC. This results in an upwelling of nutrient rich water along the Peruvian coast heading to optimum fishing conditions because of the abundance of phytoplankton. The El Nino Sothern Oscillation (ENSO) is the term used by scientists to describe the combined oceanic, El Nino, and atmospheric, Southern Oscillation, impacts of phenomenon which leads to a disruption of
Coral reefs require such a unique set of biophysical interactions that they are highly vulnerable to human-induced change. For example, just a small change in sea surface temperature is enough to result in the collapse of a whole reef system. The Great Barrier Reef is, in fact, a collection of more than 2000 individual reefs. It is the largest reef system in the world and is regarded as one of the most significant and spectacular environments on earth. 2.
The viperfish uses a process called ‘Bioluminescence’ to attract its prey. E. Its teeth also aid it in grabbing and holding onto prey that it finds while hunting in the pitch darkness of the depths of the ocean. F. The viperfish possesses a hinged skull and extremely large stomach, enabling it to rotate its head vertically to consume larger prey, in addition to the ability to consume large amounts of food when it is plentiful in supply. G. It is known to migrate vertically. Usually located in deeper waters during the daytime, whereas at night it is known to swim up to around 2000 feet.
Some study the population fluctuations in different species of fish. Biologists may also look at the complex chemical makeup of marine toxins, both natural (in poisonous sea creatures) and man-made. Some study the effects of weather and environmental changes on oceans and marine life, and try to develop solutions to the problems. One large area of concern now is climate change and the effect it will have on the ocean ecosystem. Marine biologists do both independent research and teamwork with other professionals.
The main living environment for killer whales is open oceans but they can also be found in coastal waters as well. Migration. Killer whales are very important in the oceans because they cause much of the migration of many fish and other prey. The movements of the killer whale to and from certain areas cause the other prey to move as well. Population.
