How can oil spills kill animals?

Oil spills frequently kill marine mammals such as whales, dolphins, seals, and sea otters.

Oil coats fur of otters and seals, leaving them vulnerable to hypothermia.

Moreover, how do oil spills affect animals?

One may also ask, how do oil spills kill fish? Even so, we have observed fish kills caused by spills of light oils and petroleum products (such as diesel fuel, gasoline, and jet fuel) into shallow water.

How do they clean up oil spills?

Booms and skimmers: Booms contain the oil so that skimmers can collect it. Booms are floating barriers placed around the oil or whatever is leaking the oil. Skimmers can be boats, vacuum machines, sponges or oil-absorbent ropes that skim spilled oil from the water's surface within the booms.
