Invertebrate

is Cottus echinatus. The Utah Lake Sculpin was usually around 7.1cm. The maximum length this fish was ever found was 9.2cm (Cottus echinatus Summary Page). The Utah Lake Sculpin was a pinkish transparent color. The fishes main food source was invertebrates. This fish was a freshwater species. The Utah Lake Sculpin was a bottom dwelling fish, which means it lived on the bottom of the lake (Cottus echinatus)). The environment this fish lived in was rocky, shallow areas in the Utah Lake. This fish…

D3 is produced by ultraviolet irradiation (UV) of its precursor 7-dehydocholesterol. This molecule occurs naturally in the skin of animal and milk. Vitamin D2 is a derivative of ergosterol, which is produced by some organisms of phytoplankton, invertebrates, yeast and higher fungi such as mushrooms. Vitamin D2 is not produced by land plants or vertebrate, since they lack the precursor…

In higher vertebrates, such as amphibians and mammals, two blood coagulation pathways exist which both trigger the activation of thrombin through enzymatic cascades: an extrinsic tissue factor pathway, initiated mainly by internal or external trauma, and an intrinsic contact activation pathway, which is employed to repair minor external damage and injures. The binding of tissue factor (TF) to activated factor VII (FVIIa) is essential in the commencement of the coagulation cascade, as it serves…

Giant Barrel Sponges are very unique animals. They are found in tropical areas in the Caribbean. They are benthic animals, living at depths from 10-30 m. They have the highest density cover and greatest volume of any organism living in their environment. If they are left undisturbed they can grow to massive sizes. Giant Barrel Sponges can come in many different colors also. Sponges don't move around they are stationary and stay in one place there whole life. Except when the sponges reproduce…

This report will be discussed on otters. It will describe the basic life of an otter. I will discuss All the types of otters then their diet, population, habitat, and where they live in the world. Then lastly there threats. Otters, including river otters, are the most aquatic members of the weasel family. They have short ,dense underfur, webbed feet and a slim, sinuous body. Both the ears and nostrils can be closed when The animals are underwater. There are many types of otters such as sea…

have fur. Their fur is one of the densest, softest furs in the animal kingdom--that is also water-resistant. They are omnivores with a diet consisting of crabs, abalone, sea stars, squid, sea urchins, sea worms and around 40 other bottom-dwelling invertebrates. Furthermore, to support their high metabolic rate, sea otters must eat about 25% of their body weight a day. Sea otters forage for food at the bottom of the sea and can dive up to around 300 feet. They primarily live in the water and can…

Social interaction and behavior including everything from altruistic actions towards family members to acting properly at work , is a crucial part of our life. It is important to understand the mechanisms behind why we feel an urge to behave in the way we do. Many probably wondered, why do some people cheat compulsively while others stay faithful or why some people are more “emotionally available” than others. Recently neurobiologists have made breakthroughs behind the differences in this…

Mangrove ecosystems are economically and ecologically important as renewable resources .The mangrove communities act as bio-shield to protect the coastal from natural disaster. They also act as nursery, feeding and breeding ground for many fish and invertebrate species as well as attract other kinds of wildlife. Mangrove tree are complex transition environments between terrestrial and marine systems that is a very productive plant in coastal ecosystems. Mangroves provide a shelter for a variety…

A terrestrial ecosystem is an ecosystem found only on land. There were six primary terrestrial ecosystems which are tundra, taiga, temperate broadleaf forest, tropical rain forest, grassland and desert. Terrestrial environments are segmented into a subterranean portion from which most water and ions are obtained. An atmospheric portion from which gases are obtained and the physical energy of light is transformed into the organic energy of carbon-carbon bonds through the process of…

Introduction: Due to human’s history of adverse interference, the livelihood of the normally abundant Australian Sea Lion has been affected. It is a pinniped animal, belonging to the genus Neophoca and the species cinerea.. Within this report there will be discussion of why Australian Sea Lions are considered a keystone species, including what their role is in resourcing, dominating, as well as maintaining the ecosystem they populate; scenarios of what would happen if they went extinct; how…
