piece are Chinese coins, wood, sinew and moose hide. The Chinese coins show a diffusion of cultures. Since these coins were given to the Tlingit by “Boston sea merchants in exchange for sea otter pelts” perhaps this armor represents a bond between the two groups of people—a symbol of camaraderie even. After all, the helmet resembles an abstract sea lion. Yet, if this functions as armor and warriors wear it to battle, then rival groups may identify the Tlingit with these Boston merchants. On the…

Enhydra lutris, commonly known as sea otter, is the second smallest marine mammal that lives in shallow coastal waters of the northern and eastern North Pacific Ocean. Sea otters are often found in areas with protection from the most severe ocean winds, such as rocky coastlines, thick kelp forests, and barrier reefs. They are considered a keystone species because they are crucial to the health of the nearshore marine ecosystem. Because sea otters eat sea urchins, which are herbivores that feed…

of being able to visit areas where sea otters can be sighted. Sea otters, also known scientifically as, Enhydra lutris, inhabit shallow coastal areas and they prefer places with a lot of kelp. They use the kelp surrounding them to wrap themselves in while they’re resting. They are very sociable creatures and eat animals that have shells, like clams and abalone. (www.marinemammalcenter.org/) Another common and important food source for them would be sea urchins. Sea urchins can be found all…

on a small island and fishing village off the cost of northern Norway, called Sommarøy, near Tromsø. Her father was a fisherman and her mother was a Sami from Finnmark, which also lived off the sea. From her, I have heard many stories about her experiences and the history of Norway’s connection to the sea. She didn’t go this far back, but the Scandinavians’ utilization of the marine environment is nothing new, it dates back all the way to the Mesolithic era. During the Mesolithic era, people in…

Sea otters number in the wild life is declining rapidly due to two possible problems: environmental pollution and attacks by predators. While the reading passage supports the claim that the decreasement of the sea otters is caused by the pollution, especially by human activities, the lecture points out that the assaults by the predators are the actual problem. First of all, sea otters are vurnerable to be hunted, and they have their natural predators: the orcas. It is not caused by the…

Description: o Physical characteristics of sea otters possess is the fact that they are small animals with short legs which have thick fur and short circular ears which means that they belong to the family Mustelidae[1]. The sea otters have varying fur colors from dark brown to black [6]. They are also highly social animals who travel in groups called rafts; a single raft could range from 10 sea otters to over 100 sea otters [6].  Scientific Name[1]: Enhydra lutis …

the lecture are both about decreasing sea otters population among north America's west coast. This event happened rapidly. The author of the reading believes that environmental pollution has the major role in this case. He argues that attacks by predators may be another cause, but he believes usually they hunt larger animals. The lecturer casts doubt on the claims made in the reading. He thinks predators are the most important cause of declining sea otters population. He believes orcas will…

don't have things like that so they have to improvise. The sea otter does. A group of scientist including myself have went to study the sea otter and how they function without the advantages we have. Sea otters snack on a sea snail called abalone. But the abalones shell if very hard and often not easy to break. We spotted a sea otter one day and it was laying flat on its back with a rock in one hand and a abalone on its belly. The otter began beating the abalone and cracked the shell and was…

The ancestors of the current Gitga’at people used to live in Laxgal’tsap (Old Town) in Kitikiata Inlet, an area on the northwestern side of the Douglas Channel. They lived in this area during the winter months, but used several other camps along the coastline during the warmer months. The Gitga’at had their first encounter with the Europeans in the 1870s. Their relationship remained economical until the arrival of two missionaries: Thomas Crosby and William Duncan. Many of the Gitga’at joined…

nonliving part to take out of an ecosystem is a keystone species. The sea otter is a keystone species because of how many different parts of its ecosystem it affects. One part of the sea otters ecosystem that it affects is the kelp forests in the water. The sea otter and the kelp forests have a mutualistic symbiotic relationship because with the otters eating the sea urchins, the kelp forests stay healthy and provide a home for the otters. This relationship also helps ecosystems above the water…
