Scientists have been left baffled as more and more sharks with two heads continue to surface. It is rumored the mutation was caused due to genetic abnormalities triggered by over-fishing.
According to Dailymail, the puzzling trend started in 2008, when the fisherman, Christian Johnson caught a two-headed blue shark embryo off the coast of Australia.
In 2013, a group of Floridian fishermen strained to haul in a large Bull shark, but upon gutting it found that its uterus housed a two-headed fetus.
