Introduction: The pacific sea otter, known as the heaviest members of the Weasel family, is a keystone species living in the Pacific Ocean, off the coast of Japan, Russia, America, Canada and Mexico. It’s current population, is estimated to be just over 106,000 worldwide, with just over 3,000 in California. These aquatic mammals are currently under threat of extinction. Through scientific knowledge and understanding of the sea otter, protection laws have been put into place to create for design…

specifically sea otters, blue crabs, jaguars, and as we discussed in class wolves that illustrate predators that decimate their prey because of the food chain (quora.com).” First of all, in the example of the sea otters, sea otters eat urchins. Sea urchins are omnivorous animals and therefore eat both plant and animal matter. The sea urchin mainly feeds on algae on the coral and rocks, along with decomposing matter such as dead fish, mussels, sponges, barnacles, and kelp. So, sea otters keep the…

Sea Otters Enhydra Lutris, also known as sea otters are the heaviest members of the weasel family and the second smallest marine mammals (Basic Facts About Sea Otters). Sea otters make up four different types of species: Enhydra (sea otter), Pteronua (giant otters), Aonyx (clawless otters), and Lutra (river otters) (Seaworld). Sea otters are not found just anywhere in the world. Most sea otters are found in coastal areas and islands of eastern and western North Pacific Ocean such as California,…

Sea otters spend most their time in the water. Sea otters often float on the surface of the water on their backs. Sea otters eat up to 35% of their weight in fish, crabs, sea urchins, and lobster. Sea otters eat so much that they caused the fish population to decrease significantly. If sea otters were to go extinct then there would be major effects on the ecosystem. Sea otters eat a variety of things, but a big part of their diet is sea urchins. Sea urchins eat plants. If sea otters went extinct…

people to have access to resources they otherwise would not be able to have. While trade across land was common, trade by water began to gain more popularity with the invention of better boats. One of the most well-known seas that had much trade occur upon it, is the Mediterranean Sea. Being able to access these ports, made it easier for countries, such as, China and Phoenicia, to not only receive resources they needed, but sell their own products to other societies that were in need of it.…

Sea Otters are a very well known example of a keystone predator and often utilized by textbooks to illustrate the concept. Sea Otters “Enhydra Lutris” are involved in maintaining the population of macrobenthic grazers such as sea urchins “Strongylocentrotus polyacanthus” and mussels. Sea urchins and mussels are the dominant species in these shallow water benthic ecosystems. Left unchecked, the sea urchins overgraze the benthic vegetation and the kelp forests. Kelp forests provide habitat for…

or otherwise known as the Sea otter is an iconic species that embodies the rich diversity of ocean life. As one of the major groups of the weasel family, sea otters are also one of the smallest marine mammals. Unlike other mammals, such as whales and dolphins, Sea otters do not have blubber, instead they have one of the thickest and densest coat of fur. This fur coat holds up to almost one million hairs per square inch (Ravalli, 2010). With this amount of hair, the Sea Otter is able to maintain…

1) After looking at the graphs in Figures 3 and 4, it is obvious that killer whales are the cause behind the deaths of a large amount of sea otters. Despite the data for Figure 3 showing all sea otter the researchers encountered, while the data for Figure 4 showing sea otters with radio tags, both figures still show a drastic decrease in sea otter population with the only main difference between Kulak Bay and Clam Lagoon being the ease of access that killer whales have to the areas. The…

Salton Sea is the largest inland body of water in California, measuring at 35 miles long and 15 miles across. Its salt level is fifty percent saltier than the ocean itself. The Salton Sea is beneficial to more than four hundred and twenty different species of birds. The species range from “white and brown pelicans to eared grebes, curlews, ibis, avocets and snowy plovers. It also supports millions of fish and a host of invertebrates, important food sources for the birds.” (Blogger, 2015) Salton…

OUTLINE In this essay I will attempt to examine the nature of Aral Sea Disaster that implicates in ecological, social, economic, and cultural environments analyzing the root causes of the disasters in terms of mitigation, adaptation, and rehabilitation practices that will challenge the traditional view of a crisis as of “natural” process, but rather “constructed”. I will tackle the historical background of a disaster, its occurrence, consequences and effects, and ultimately identify strategies…
