This is caused by oils with a high viscosity, in other words heavy oils. Marine systems are by their very nature open- that is connected by the sea, wind and currents to distant uncontaminated regions.
Larvae of tuna and other fishes eat anything they see in the water, including oil droplets. Chemical dispersants are likely to impact deep-water animals downstream of the well. Although such catastrophic events are very damaging and economically expensive at a human scale, on an ecological time scale they are passing disruptions and on an evolutionary timescale, barely perceptible.
Contaminants from the spill and the dispersants are likely to concentrate in the upper food chain, affecting whales, dolphins, birds and sharks.
In the well studied cases in the Arabian gulf, Alaska Exxon Valdez and English Channel Torrey Canyonthe appearance of the system returned close to normal within a few years. This natural variability means it is unlikely that exact pre-spill conditions will be reached.
Studies on a variety of fish larvae suggests that ingestion of both oil droplets and dispersants causes adverse effects, including mutations, physiological problems and increased mortality.
In shallow water these toxic substances may directly kill algae, coral and sea grasses. Many marine organisms have mobile life phases floating eggs, larvae that recolonize and re-establish populations. However, more detrimental is the niche in the community being replaced with organisms performing completely different functions thereby altering the ecosystem dynamics.
For example, shallow coral reefs are some of the most dynamic environments, frequently exposed to the intense forces of typhoons and tsunamis. Many species of birds, including the brown pelican just taken off the endangered list face threats from the oil spill on the coastal islands and wetlands of the Gulf that they use as rookeries.
Coating with oil is particularly devastating to birds.
A thick film of oil on the sea surface may reduce sunlight penetration and reduce photosynthesis.
