Dear student..
Oil destroys the insulating ability of fur-bearing mammals, such as sea otters, and the water repellency of a bird's feathers, thus exposing these creatures to the harsh elements. Without the ability to repel water and insulate from the cold water, birds and mammals will die from hypothermia.
Many birds and animals also ingest oil when they try to clean themselves, which can poison them.
Fish and shellfish may not be exposed immediately, but can come into contact with oil if it is mixed into the water column. When exposed to oil, adult fish may experience reduced growth, enlarged livers, changes in heart and respiration rates, fin erosion, and reproduction impairment. Oil also adversely affects eggs and larval survival.
Hope this helps! Cheers!

oil is lighter than water thus it floats on the surface of water,blocking the sun rays which are essential for the marine animals.Without sunshine marine animals feel asphyxiated thus, oil spill disables them to breathe.
the oil pollution causes harm to the marine birds because at times they also swim over the contaminated water.
