While natural genetic mutation is one of the possible causes for this shark having no skin or teeth, perhaps there is another, more sinister reason? Some scientists feel that this mutation could have happened because this shark was exposed to chemically contaminated water for a long duration of time.
It is a widely known fact that ocean water that is polluted with harmful chemicals can cause fatal genetic damage in sea creatures. These chemicals and pollutants get deposited in the bodies of the fish and can lead to serious birth defects and mutations in the next generation. While researchers are not sure if this is the actual cause, it definitely is one of the possibilities.
