Giant Otters Essay

Orcas are the “most social mammal on Earth,” (Hogenboom). In the wild, orcas are born into a pod and will live in the community their entire lives. They live coherently and will cooperate with each other without issues. Each pod develops its own unique culture and creates the closeness and social dependence only witnessed in the wild. Rarely will a lone orca be seen outside of the aquarium setting. These animals thrive on having a large community to depend on their entire lives. They will swim and play together because it is vital to their quality of life and survival. (Hogeboom). In contrast, orcas who have been captured or bred in captivity, often live in what is comparable to a swimming pool or a bathtub. Size is not the only issue with orcas being held captive; they have synthetic interactions with their handlers and other orcas that inaccurately resembles

Otter’s scientific name is Lutrinae. The Sea Otters are the most common name known, they live in fresh or salt water depending on their species. Some Otters live in extremely cold habitats and tend to be active during the night. The Otters population has been extremely low since the 1970’s when they were hunted for fur trade, but because of the International Fur Seal Treaty of 1911 many attacks have decreasing. Otters population has not been reaching its full potential because of four main reasons; fur trade still exists today, competition on seafood, pollution and global warming, food limitation, and oil spills have become a major factor in the lives of these sea creatures.

Baby harp seals are disappearing in population because of the climate change going on near their habitat. These pups are constantly drowning and being crushed by melting ice every day. If this keeps occurring, they will quickly stop breeding and eventually become extinct. Although they are not endangered, baby harp seals are passing by the minute. If you think this is unacceptable and want them to be saved: choose energy efficient appliances when making new purchases, replace a regular incandescent light bulb with a compact fluorescent light bulb, use a clothesline instead of a dryer when possible, cover your pots when cooking, and speak up to the public about how others can do these things too!

One, exploratory is known as the type of play that familiarizes the environment to the kitten. Two, social is behavior done with others at a young age such as biting, wrestling, and rolling around on the floor. Third, object is known as using the paw to help them discover coordination. They do this by looking and playing alone or with others when going after specific objects.

Firstly, the author states that pollution sources such as oil rigs near Alaskan beaches is killing the sea otters. Also, a research held on water samples in the area showed that it contains high levels of chemicals that may indirectly kill the otters. This view is objected by the lecturer. He proposes that Orcas use the animals as source of food, that is why there are no signs of dead otters on shores of Alaska, which would however be

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

the manatee is an obvious disadvantage. A fast oncoming boat may not be seen by

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.

The reading suggests that two possible causes: the environmental pollution and predators attacks. However, the lecture defends that is more probabily is the predators attacks.

I discovered I am an otter. Otters tend to be focused on a problem and zone others out. Otters are not lazy, but easily distracted can be any way to describe us. We feel entitled to bring good into the day and if you want to impress us, just simply take us out to eat. Sadly, we have a fear of failure so this can prevent us from truly reaching out potential.

They may go down one-hundred feet or more in search of food such as crabs, snails, sea urchins, mussels, abalones, and clams (McDannald 478). They require a substantial amount of food to maintain a high metabolic rate. This rate is essential for the sea otters to generate body heat. Sea otters will consume twenty-five percent to thirty percent of their body weight to maintain this metabolic rate.

This essay will outline the theoretical rationale for play in the development of young children. Boushel, Fawcett and Selwyn (2000:57) state, ‘Play is not easily defined...’ Play means different things to different people. Rubin, Fein and Vandenberg (1983) {cited in Hughes, 2010} suggest play should be intrinsically motivated, freely chosen, pleasurable, non literal and actively engaging. Play gives children freedom of choice, it allows them to lead their own learning, follow their own learning intentions and express themselves freely. There are many reasons that lead us to believe play is crucial for child

We don’t join two distantly related groups because their members have independently evolved some similar features. Humans and the bottle- nosed dolphins for example share the same pinnacle brain size among mammals. Dolphins are more closely related with whales and humans are more closely related with apes. We follow the same principles with our own genealogies. For example a boy with Down’s syndrome is still his parents son and not by the reason of his affliction, more closely related to other Down’s syndrome children, no matter how long the list of similarity features. Zebras exist in three species, all with black and white stripes, but differ with in numbers of stripes and patterns. The three species are all members of the genus Equus, as

Sea otters have been dieing at a high rate these past ten years. Scientists belive that bacteria is to blame, so it could infect our water aswell. Also, sea otters tell scientists a lot aboutother species in there enviroment, like fish, fish could be affected by otters leaving! As a matter of fact, sea otters are very smart sea mamels, if they want food, like clams, they can wedge the clams out of a tight spot, like rocks.
