National Geographic has reported the discovery of a two-headed shark that has shaken people the world over.

A few years ago off the coast of Florida, fishermen pulled in a bull shark whose uterus contained a two-headed fetus. Another fisherman discovered a two-headed blue shark embryo in the Indian Ocean.

Blue sharks have produced the most recorded two-headed embryos because they carry so many babies—up to 50 at time, says study leader Felipe Galván-Magaña, of the National Polytechnic Institute in Mexico.

More and more of these two headed sharks seem to be showing up all of a sudden and could be a strong indicator of the disastrous impact that climate change has on our Oceans & seas.

A genetic disorder seems to be the most plausible cause for the two-headed sharks but the malformations could come from a variety of factors, including viral infections, metabolic disorders, pollution, or a dwindling gene pool due to overfishing, which leads to inbreeding, and thus genetic abnormalities.

If the two-headed fetuses are more prevalent in nature, then overfishing is a strong culprit as it may cause the gene pool to shrink.

Either ways it is a strong reminder for all world leaders and people across to do whatever is required to save our one and only Planet Earth.
