Yet small oil spills and leaks, such as a damaged jet ski, leaking motorboat, illegally dumped quarts of motor oil, or runoff from road pollution can be just as deadly to birds and other wildlife. “Experimental and Modeled Thermoregulatory Costs of Repeated Sublethal Oil Exposure in the Double-Crested Cormorant, Phalacrocorax Auritus.” Marine Pollution Bulletin, vol. Effects on marine life : oil spills have negative impact on the marine animals. Since most of the oil floats in water, the sunlight absorbing capacity of the water decreases. Attempts to remove the oil through preening also causes birds to swallow oil, which causes severe organ damage.

Some of the soluble components and emulsions are poisonous, particularly to small organisms that do not have protective coverings or shells- Fish larvae, single celled algae and many kinds of plankton are vulnerable and these are the basic foundation of the marine food chain. Despite massive clean-up efforts following the 1989 Exxon Valdez oil spill, for example, a study conducted by the National Oceanic and Atmospheric Administration (NOAA) found that 26,000 gallons of oil were still trapped in the sand along the Alaska shoreline.
