Animals can also be internally diagnosed via necropsy by identifying petroleum hydrocarbons in their fat, liver, or kidney tissues [2] For damage assessments, the death of the animal must have occurred after the oil spill. [1] The severity of damage directly correlates with the amount of oil spilled and the animal's exposure to oil. [4]
The oil spill directly affected Atlantic bluefin tuna, as approximately 12% of larval tuna were located in oil-contaminated waters, [9] and Gulf of Mexico is the only known spawning grounds for the western population of bluefin tuna.

Mnemiopsis leidyi, a species of comb jellyfish that spread so it now inhabits estuaries in many parts of the world, was first introduced in 1982, and thought to have been transported to the Black Sea in a ship's ballast water.

When oil spills occur, the affects can be felt in an area for decades and can cause massive damage to the aquatic life. For aquatic plant life an oil spill could affect how light, and oxygen is available for photosynthesis. [100] Coral Reef Community.

Oil spills are one of the most emotive of marine pollution events. However, while a tanker wreck may result in extensive newspaper headlines, much of the oil in the world's seas comes from other smaller sources, such as tankers discharging ballast water from oil tanks used on return ships, leaking pipelines or engine oil disposed of down sewers ...
However, the removal of oil on shore took over a year until the late spring of 1997. Small amounts of oil were still found beneath the sand on sheltered beaches and in rock pools in 1999 – three years after the spill. The effects of the spill were not as bad as initially predicted. This was due in part to the time of year when the spill occurred.
