marine otter vs sea otter

There are other important differences between these two species as well: Northern sea otters are found only in coastal areas, with a range that extends north from the Washington coast, along the outer edge of Vancouver Island, and up to Alaska. First, sea otters are two to three times the size of river otters—and, when at the water’s surface, they float on their backs, while river otters swim belly down like most animals. Sea otters are foragers that eat mostly hard-shelled invertebrates, including sea urchins and a variety of clams, mussels, and crabs. This species is aptly named because sea otters rarely come on land. They are the heaviest member of the weasel family, Even though they are the second smallest marine mammal. In recent years there has been much effort put into returning sea otter populations to previous numbers with conservation programs and re-introduction projects. Sea otters, as the name suggests, are marine animals, and they live just off the coasts of the Northern and Eastern Pacific Ocean. Because Sea Otters spend so much time in cold waters, they have a very dense layer of fur as opposed to a thick blubber layer like whales, sea lions and seals. Sea otters rest by wrapping themselves in kelp to keep from drifting away.

They are occasionally seen along the Straits of Juan de Fuca near Port Angeles, but they rarely venture further inland than that. These animals spend most of the time in the water, but they can move around on the land also. Based on the sequence data presented here, our results suggest that otters are divided into three primary clades that include: (1) the North American river, neotropical and marine otters; (2) the sea, Eurasian, spotted‐necked, cape clawless and small‐clawed otters; and (3) the giant otter. One of these otters is the Sea Otter, which is found in the Pacific Coast of North America. They are most known for floating on their backs with a stone on their chest. They also scavenge for garbage, bringing them into close contact with people. What does an Otter eat?

Sea otters prey on sea urchins, thereby preventing sea urchins from overgrazing the kelp forest. In the years from about the 1740s and the early 1900s, the population of sea otters plummeted from about 200,000 animals to just about 2000 due to their being extensively hunted and killed for their thick fur. But instead, I held back and listened to the conversation, thinking back to ten years ago or so when I first saw river otters in the ocean.
