Read the excerpts from the two articles on sea otters.

Article A

Sea otters live in the chilly Northern Pacific Ocean and spend almost all their lives in the water. They sleep, hunt, groom, mate, and give birth in the ocean, where they float on their backs on the water's surface. Adult sea otters spend more than a third of their day grooming their fur. This isn't for vanity; it's for survival. Unlike most sea mammals, sea otters do not have an inner layer of fat to protect them from the cold water. These creatures rely on their dense fur to protect them from the low temperatures. Sea otters have one of the thickest furs in all of the animal kingdom. An adult sea otter's coat can contain up to 1 billion individual hairs! These hairs form a protective, waterproof layer, which traps air and provides insulation. It is crucial that a sea otter's fur is kept clean to maintain this insulating layer between the water and their skin.

Article B

Oil spills from off-shore drilling and shipping are also an immense threat to sea otters. Sea otters are dependent on their thick fur to keep them warm. Its unique structure traps air that insulates their bodies from the cold water. When an otter's fur is covered in oil, it can no longer keep the otter warm. This can cause hypothermia and even death. If the otter tries to clean its fur, it will ingest the oil, which is poisonous. In 1989, the Exxon Valdez hit a reef in Alaska. The ship spilled over ten million gallons of oil into the ocean. The U.S. Fish and Wildlife Service believes that anywhere from 4,000 to 10,000 otters died due to this oil spill.

How are the authors' points of view different in these excerpts?

Article A focuses on the importance of the sea otter grooming its fur, but Article B shows that the sea otter's grooming habits endanger it when the water is not clean.
Article A explains that adult sea otters spend more than a third of their day grooming, but in Article B, the author explains that adults spend most of their day caring for their young.

Article A highlights the different reasons the sea otter's fur must be clean, and Article B highlights the actual process sea otters use to keep their thick coats clean and healthy.

Article A focuses on how the sea otter's fur can harm the animal, while Article B focuses on how the sea otter's fur can protect it from oil spills and other water pollution.
