How long does oil last in the ocean?

When oil enters the water from natural or manmade sources it begins to degrade, taking anywhere from days to decades depending on conditions. Processes that spread the oil through the environment usually speed up this degradation. However other factors such as colder water temperatures can inhibit these processes.

Which creatures are most affected by oil spills?

Since most oils float, the creatures most affected by oil are animals like sea otters and seabirds that are found on the sea surface or on shorelines if the oil comes ashore. During most oil spills, seabirds are harmed and killed in greater numbers than other kinds of creatures.
