Otter

The study conducted by Weisle, Nagaswami, and Peterson is displayed about river otters and how they are different in structure from other marine mammals. River otters must depend on their thick layer of hair for survival. River otters are semi-aquatic mammals, which are considered to have denser fur than any other mammals. It’s thick, sleek coat, which keeps it dry and warm, is made up of two types of hair. The longer outer hairs are water repellent as known as guard hairs, and the other is underhair

The North American River Otter is one breed of the Lontra, or otter. This animal is a quick, intelligent, and clever hunter. Although hunted for their beautiful pelts, river otters are still found in almost every region. They are smart and playful, and very outgoing creatures. This paper, will discuss why river otters are one of the most amazing animals. The river otter’s appearance and physical build are made for aquatic life. They are slim and streamlined creatures, specifically made for cutting

such species is the sea otter. The sea otter has an important role in the ecological preservation of pacific kelp forests. Sea Otters contribute towards the overall health and well-being of the ecosystem they inhabit. The sea otter is an important predator in the nearshore marine ecosystem of the North Pacific Ocean. It is considered a “keystone” species in the ecosystem. They limit the prey populations of a variety of marine invertebrates that reside near the shore. Sea otters “have large-scale community

How Do Sea Otters Help The Kelp Combat Climate Change? “Atmospheric carbon dioxide (CO₂) concentrations have increased by approximately 40% since the start of the Industrial Revolution” (Wilmers et al. 2012). This increase in atmospheric CO₂ is a leading cause and contributor to Earth’s climate change with effects such as: “measurable global heat retention and elevated atmospheric temperatures, partial melting of the polar ice caps, ocean acidification, and a host of other impacts on Earth’s environments”

A sea otter is the smallest marine mammal in North America, and is a part of the weasel family. They range along the coast from San Mateo County, and South ward through Monterey County, down through Santa Barbara county. Most animals don’t have fat on them, unlike a sea otter which has blubber to keep them warm, which is very thick. It keeps the otters warm in negative degree waters. Their fur is made up of million hairs per square inch. Only way they keep their coats waterproof, which they

Introduction Sea otters, (Enhydra lutris), are considered a keystone species, and for this reason, can be useful indicators of nearshore ecosystem health (Kreuder et al. 2003). With the implementation of the Marine Mammal Protection Act, southern sea otter (Enhydra lutris nereis) populations within their California range rebounded from post fur trade levels of approximately 50-60 in 1938, to more than 3000 today. However, growth rates have been slower than expected for this population (Riedman

1700-1800s sea otters were nearly hunted to extinction. They became listed under the Marine Mammal protection and Endangered Species Act and the gained protection with the signing of the International Fur Seal Treaty of 1911. Sea otters eat many of the same shellfishes that humans like to eat, such as sea urchins, crab, and lobster. Since sea otters like to eat the same kinds of food we do they often find themselves in the same areas where fisherman fish at. Some shell fishers see the sea otters as a competition

Endangered: Sea Otters         You may know Sea Otters as just cute and cuddly animals that float on their backs all the time, but they are definitely more than just that… Did you know that Sea Otters are a keystone species! They eat sea urchins and invertebrates, and those sea urchins would just eat up all kelp forests if their populations were all over the place. You may think that kelp forests aren’t that important, but they are, they support hundreds of species from sea stars to sharks. Sea otters also

Describe the biological mechanisms through which global warming can influence the Sea Otter (Enhydra lutris). In today’s society, global warming is a serious issue and more attention needs to be drawn to the impacts of this issue and how we can help lessen the intensity of these impacts, especially on organisms. These changes in global temperatures have had a great effect on the biological mechanisms through which organisms are distributed in their habitats and the redistribution of species can cause

activities have decreased the population of the Sea Otters, and negatively impacted the trophic levels of the ecological pyramid they belong in. Primarily after the industrial revolution, humans have constantly overexploited the environment, resulting in the gradual loss of biodiversity. Among these struggling organisms are the sea otters, an essential support for trophic levels including the sea urchins, kelp forests, and others. Without otters, dependent marine animals in different trophic levels
