would say, for the Sea Otter. Sea otters, are a common animal most people hear about, but not many people actually know about. This is all about a sea otters history, an ecosystem, and why they are in fact endangered. Sea otters however have made a comeback and for the majority are not at risk anymore and aren't expected to be anytime soon. Sea otters are a very common yet diverse animal. They are the only aquatic member of the weasel family. Since the 1970's sea otters have become much more
Monterey Bay Sea Otters There are a number of sea otters who are an important part of this world and they form a fairly large population and that is why it is felt that they should be preserved at all costs. They are an important source of earning for the people and they are also important in the sense that they provide an important source of earning to the people and their is an entire group of people who use this field as their source of earning. Besides the population of these otters keeps fluctuating
Introduction Sea otters (Enhydra lutris) are marine mammals capable of spending their entire lives in water. Being carnivorous in nature, they feed on sea urchins, crabs, fishes, mussels and clams. They are referred to as keystone species due to their profound impact on marine ecology. The interaction between sea otters, sea urchins and kelp forests has been studied as a model for the impact of predator-prey interactions on community
1. If the southern sea otter became extinct primarily because of human activities, it would be unethical and people could no longer be able to look at these appealing and highly intelligent animals as they play in the water resulting in the loss of millions of dollars a year in tourism revenues. Also, sea urchins and other kelp eating species would probably destroy the Pacific coast kelp forests and much of the rich biodiversity they support. I would do the following three things to help prevent
Sea otters (Enhydra lutris) are marine mammals indigenous to the North Pacific Ocean (Larson et al., 2015) and are members of the weasel family (Defenders.org, 2016). They are a keystone species in the kelp forest ecosystem (Defenders.org, 2016). Sea otters are considered an endangered species under the International Union for Conservation of Nature (IUCN) red list (Doroff and Burdin, 2015). At their highest point sea otter populations ranged from several hundred thousand to over a million (Defenders
Giant Otter The mammal that I have chosen is the giant otter. I was interested in this mammal because I did not know there was such thing as a giant otter. I mostly thought that there were just normal sized otters. Now I’m intrigued to know what the giant otter’s life is about. Where are they from? I will be finding out this information later in my paper. They are nice, but violent creatures. The giant otter species is lutrinae. The lutrinae is a branch of the weasel family Mustelidae. That family
Southern Sea Otter Population Decline The major threat to the Sea otter was the oil spills. The sea otters, especially the southern sea otters become hypothermic when oiled. What contributed to their vulnerability to oil is that their fur can lose insulative property, meaning they lost the ability to store things. Oil can be ingested whilst grooming, which leads to gastrointestinal diseases, other ailments, and death. Volatile components of oil inhalation causes lung damage. Sea otter fishings are
Save the World: Save the sea otters During the 18th and 19th centuries, sea otters were hunted for their luxurious pelts, and by the early 1900s, the species was believed to be extinct in California. (Carswell) Why do we care you ask, well not only are they super cute and eat with their hands. Apparently, a healthy population of sea otters keeps the sea urchin population in check. An unhealthy or small population of sea otters allows the sea urchin’s number to explode thus decimating kelp beds
cuteness of otters is worldwide accepted. These creatures are fuzzy, social, and incredibly intelligent. Male otters are called boars, females are sows, and the babies are called pups. This essay contains a brief synopsis of the types of otters, the anatomy of an otter, the threats they face, its social nature, motherly instinct, how it eats, and its daily life. Otters are members of the Mustelidae family, and they are the largest member of that group. There are 13 species of otters found all around
peace between nations. Globally overfishing is an issue that all must consider and not abuse. The sea is a limited resource that has many reprocutions when abusing the sea. Whole ecosystems can be destroyed by something as simple killing off the otters. There are people that manage overfishing and can calculate if a nation is lying about the amount of fish there are being caught. Common Curtseys can be overfished in certain regions of the world and that can affect the migrations of something like
Sea Otters are critical to ocean life, but their population is decreasing. Oceans today are home to thousands of creatures. With so many different species, could you imagine that one of them would be a part of the weasel family? The Sea Otter is that animal and it is critical to oceanic life. Unfortunately, their population has been declining for many years. Sea Otters can live on land, but their main habitat is in the water. Sea Otters are the biggest animal in the weasel family, but the second
primary producer (Mills et.al. 1993). Sea otters, which typically live in tidal areas off the western coasts of the United States and Alaska, are a common example of a widely studied keystone species. Sea otters, or Enhydra lutris, are keystone species to kelp forests because of their importance in maintaining the food web structure. They are top marine predators that are easy to observe because they live close to the shore (Laidre and Jameson 2006). Sea otters have low reproductive rates and have fragile
Just north of Vancouver Island, there is an archipelago of islands shaped like an upside down triangle. Sitting just east of the Pacific fault line, experiencing upwards of fifty inches of rain per year, wind speeds as fast as 165 km/h, and heavily populated with trees weighing as much as three blue whales, one would expect the most turbulent part of these islands to be the environment, but they’d be wrong. The history of Haida Gwaii is one of the most complex and bloodiest in Canadian history. John
Island of the Blue Dolphins by Scott O’Dell In the Pacific there is an island shaped like a big fish sunning itself in the sea. Around it, blue dolphins swim, otters play, and sea elephant and birds abound. A young Indian girl lives and waits for her people to return for her, from the land to the east. Karana with her long black hair and her dark skin, held her own on an island after her people had left for a new place. She was sure they would come back the next spring, but after two springs she
first recall realizing the vastness of ecology at age three when my family lived on our sailboat, Euminides, for three months. Being on the boat allowed me to skate on top of the waves in the company of our neighbors: seals, pelicans, whales, sea otters and once even a great white! Witnessing the water
sea otters are from the kingdom animalia. Sea otters are stouter and have large rib cages, smaller tails and muzzle than other species of otters. Yet sea otters posses the fine, dense fur coats characteristic of the Mustelidae. Their forefeet are small and dexterous with retractile claws and the flipper like hind feet are broad and webbed. Sea otters once was abundant along most coastal North pacific ocean. That was before fur traders hunted them for their thick ice, luxurious pelts. By the year
The role of the sea otter (Enhydra lutris) as a keystone species has been studied for years. Studies have strongly discussed the function of this animal that, though few in number, have created large impacts in the ecosystem in which it inhabits. Their main choice of habitat lies in kelp forests due to the kelp’s effect on the reduction of wave action and their closeness to rocky shores which provide habitat for otter prey (Schiel and Foster, 2015). Sea otter impacts can be seen through the phenomenon
candensis, river otters, use their pheromones in a behavior commonly referred to as scent marking. River otters are semi-aquatic, carnivorous mammals that live mainly in inland waterways, ponds, and lakes. They are most well-known for their playful antics, and they can be observed playing in their natural habitats throughout North America.1 Scent marking is a behavior that has been observed in several different animal species, particularly mammals, but for otters it is very strange. Otters are semi-aquatic
Deborah Butterfield's "Otter" (2014) horse sculpture expresses a realistic display of beauty and craftsmanship because of its life-size image, the symbol of strength and the spirit it exerts where it is displayed at the Art Hotel in Denver, Colorado. "Otter" is a massive horse, standing at the entrance of the hotel, gazing toward the patio, looking as if it is going to trot right out the patio door. Deborah, born in San Deigo, California now lives in Montana and Hawaii. Montana and Hawaii have
Imagine discovering a village near the ocean the same way as its inhabitants left it hundreds of years prior. Almost as if life paused and resumed a couple centuries later. Untouched and undamaged, just like they left it. The Makah was a Native American tribe who inhabited Washington in the 1800’s. The Makah were skilled fishermen and hunters. Around 1560 five lodgehouses in Ozette were buried due to a mudslide. The mudslide maintained the houses in low oxygen which cause the items to be perfectly
