Hearing the words ‘two-headed shark’ sound like a title of an upcoming shark movie. But it really does exist and scientist says that it keeps popping up in different parts of the world!
In Florida a few years ago, a fisherman brought a shark with a two-headed offspring in its uterus. Then in 2008, a fisherman found in the Indian Ocean a two-headed blue shark embryo.
In the Gulf of California and Northwestern Mexico back in 2011, conjoined blue shark twins were caught. Study leader Felipe Galvan-Magaña of the National Polytechnic Institute in Mexico said that Blue Sharks are recorded to have most produced two-headed embryos due to carrying up to 50 offspring.
According to the new study of the Journal of Fish Biology, an embryo of a two-headed catshark in the Atlantic was identified by Spanish researchers. They noticed that there is an odd embryo in a see-through shark egg in a raised for human-health research in a laboratory.
If you think that this is just your average two-headed-beast, well you’re wrong. National Geographic says that, “it’s the first such specimen known from an oviparous shark species, or a shark that lays eggs.”
Study leader Valentin Sans-Coma together with other researchers opened the egg for them to study the specimen. Then Study Leader Coma said that they still can’t identify if the animal would have survived because it was the first time that they found a conjoined twin in a shark that lays eggs.
