Two-headed sharks may seem to be a rare phenomenon, but they do exist. To make matters even more surprising, a growing number of such sharks have been spotted in many years of late; however, scientists are perplexed for their springing up in huge numbers.
If you thought it is safe enough to swim again in the ocean with sharks, then how about meeting a two-headed shark while enjoying your swim? This can be a terrifying thought. Scientists have recently found such one-of-a-kind, but lucky enough, it's a really rare case, and it won't eventually survive into an adult shark.
