Southern Sea Otter Research Paper

One of the most fun, visually amazing functions to visit are zoo's. Growing up as a kid going to the zoo was so much fun and basically guaranteed a great day out. People have been complaining and questioning the role of zoo's for a long time now. Some claim that it actually kills the animals off faster. Others claim that zoo's actually help protect and preserve the lives of these animals. Only one can make a reasonable argument by studying sources, and finding out statistics. Based off of the articles, "The Stripes Will Survive", "The Zoos Go Wild", and "Our Beautiful Macaws and Why They Need Enrichment", we can truly get in-depth analysis about the role zoo's play.

Zoos across the world claim to be safe, suitable homes that replicate habitats of animals that are usually found in the wild. However, there is no possible way for wild habitats to be replicated well enough for animals in captivity to thrive, animals are often separated and withheld from living as they would in the wild. Despite their argument of being educational for visitors, the only thing they are teaching the public is that it is ok to take animals out of the wild and lock them up for their own enjoyment. Regardless of these claims, zoos are inhumane.

As a child, many people would often go to the zoo or to the circus and see animals in real life. In circuses, animals would often perform tricks and stunts, dazzling the audience. In the zoo, people would often see animals in their native habitat, or what looks like it. Children were mainly amazed with the animals and were always exited to go see the animals. As the years go by, they start to realize that some of the animals are suffering and are being mistreated, especially in circuses. They see that the animals in zoos are depressed and lonely and the animals in the circuses are chained up. What is worse is that animals in laboratories are often treated very poorly; more poorly than what Americans treat prisoners and refugees. There have been many debates on whether animals should be held in captivity. Some groups believe that animals should not be held in captivity because they have the same capacities as humans. They believe that animals can feel emotion and have a sense of morality. Animals in captivity are deprived of their natural habitat and their instincts. Animals raised in captivity tend to rely more on humans compared to animals raised in the wild. They also believe zookeepers and trainers are putting themselves at risk when taking care of the animals. There have been many incidents including the death of trainers by animals, one highlighted by the movie “Blackfish” by director Gabriela Cowperthwaite. There are others who believe that putting animals in captivity is beneficial for not only the animal, but for humans as well. Humans get more jobs if more animals are put into captivity because there is an increase in the amount of people needed. Another benefit of keeping animals in captivity is that it could help save a species who is endangered and close to going extinct. Another benefit is that it helps increase the amount of food available because some animals are raised for food. Putting animals in captivity wrong unless they are being used for the animal’s benefits.

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 guard hairs could provide some protection for the more delicate underhairs. The three authors of this article, “River otter hair structure facilitates interlocking to impede penetration of water and allow,” addresses a question upon why the

Countless land and aquatic animals are held captive in zoos. However, are zoos really conserving wildlife like they say, by putting animals on display? Negative. Zoos are unsuitable environments for wild animals, and therefore should be eradicated. Zoos should cease to exist for three main reasons: animals deserve just as much freedom and happiness as humans, enclosing them in confined habitats harms them, and imprisoning them infuriates them.

Southern sea otter lives in kelp forests (a type of seaweed) along the Pacific coast, mainly off the coast of California. The marine mammals consume on average one-fourth of its weight daily including sea urchins, which are vital to support the kelp forests. By the result of sea otters preying on sea urchins, the consumption of kelp by sea urchins are kept at a constant rate allowing the forest to grow and thrive. This is highly important for biodiversity in the sea that is provided by the kelp forest, which is a key component of the three principles of sustainability. There are three ways that human can do to help prevent the premature extinction of southern sea otters. First, ethical issue that consists of the species being seen as vital

There are 16 different breeds of otters. Sea otter, Eurasian otter, Lutra, Lontra, oriental small clawed otter, Giant otter, smooth-coated otter, African clawless otter, Northern River otter, Asian small clawed otter, Congo clawless otter, marine otter, neotropical otter, South American otter, spotted-necked otter, and hairy nosed otter. This animal is pretty much always near water, they are usually found near both freshwater and coastal marine, such as, lakes, rivers, inland wetlands, coastal shorelines, marshes, and estuaries. Otters can be found in North America & other places as well. Otters eat fish, crabs, sea urchins, abalones, clams, mussels, and snails. They are preyed on by bobcats, coyotes, mountain lions, wolves, black bears, and

The sea animal I chose was a southern sea otter. Sea otters inhabited the North Pacific Rim of the Pacific Ocean, from Hokkaido, Japan, through the Kuril Islands, Kamchatka Peninsula, Commander and Aleutian Islands, Alaska, and south along the west coast of North America down to Baja California, Mexico. Scientist have evidence found in fossil records, that sea otters and their relatives have been a major part of the California’s ecosystem for the past five million years but by 1830 sea otters became very rare in California. Scientific evidence to suggest Otters have been on Earth for the past 23 million years. It is speculated that the Otter as it is today could have evolved monumentally about 7 million years ago.

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 and Estes 1990). Definitive explanation for this is unclear, but contributing factors may be that sea otters face a range of physiological and environmental challenges to reproduce.

Many people have memories of visiting a zoo or an aquarium in their childhood, but are they safe for the animals inside? Indicators for both support and opposition exist, making the debate double sided and more complex than originally thought. For example, SeaWorld recently shut down their orca breeding program because the whales were being harmed. Despite this, animals in captivity may be a necessity. Habitats being destroyed and the threat of predators and poachers are becoming more common. Zoos and aquariums can provide a safe haven from these dangers. Alternatively, some zoos and aquariums can be even more dangerous for the animals than if they were in their natural habitat. Mistreatment of animals in captivity is a problem that only seems

Sea Otter's are members of the weasel family can be found along the coast of North America. A sea otter spends most of its time in the water and the rest of time it comes to land to sleep. Sea Otter floats on its back to the land and sleeps like that also. They have webbed feet. Their fur keeps them warm and it doesn't shed. Sea Otter's is one of the smallest marine mammal. They have a large amount of different adaptations. These different adaptations help them survive in their marine environment. Their long whiskers help the, detect vibrations in water and sensitive forepaws. Their claws helps them groom themselves and capture their prey underwater. The male is bigger than the female. Sea Otters have a high metabolism they eat 25% of their weight in food each day . They are also known for eating a clam and a rock that has been gently caught from the ocean floor. The otters place the rock on their chest and constantly smash the shellfish against it until it breaks. Once its broken they eat it . They also like to eat crabs , squid , octopus, and fish.

River Otters are a species found on 5 out of 7 continents in the world. They have short legs that allow them to swim, walk, groom, and manipulate their pray effectively. Generally, they are various shades of brown, but they have a darker dorsal, and a lighter ventral. Their head, eyes, ears, nose, and teeth are beneficial for them when hunting prey, and when being hunted. River Otters have unique characteristics, features, and lifestyles that allow them to be not only adorable, but important to many ecosystems.

“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” (Wilmers et al. 2012). Earth’s ecosystems are combating this climate change by helping reduce the concentration of CO₂ and “sequestering C” (Carbon) in the atmosphere through “photosynthesis” (Wilmers et al. 2012). “Kelp forests are among

A chestnut colored, furry blur races past you as you are paddling your boat in a North American lake. You wonder what it could be! It is a river otter. In this essay, I will be telling you about this interesting member of the weasel family.

Some people agree that animals should be kept in the zoo. They said it would be safer for the animals and they won’t be extinct. The amount of possibilities of them dying, shot by hunters or any other reason, still higher than the chances of their survival. Food and shelter are provided, medicine, and their breeding is being controlled. And many of the wild animals in zoos are ones that are on the endangered list as their amounts are rapidly diminishing. Letting them loose and returning them to the wild is not necessarily a safe option. (Mylot, 2007) In fact, zoo can be one of the educational studies for children and people who are interested with animals. Zoo is the only place that we can have an opportunity to see animal’s life really close and sometimes we can touch them. Zoos also provide lots of information about certain animals, children can have chance to get out of the classroom and learn so they can see natural beauty from different species of animals. Even children can see them from discovery channel but that’s really different if you see animal in real world, for an example, if you see crocodile, snake or shark in the movie, maybe you won’t afraid than you see the real one. According to Tudge, (1992, p.56) Zoos are the place where people can study animals and their habitat, even scientist don’t need to go
