In a rare sighting, scientists recorded the image of a scary shark with a bluish color and gray that was swimming in the waters of the northern hemisphere. "The ghost sharks" recorded was actually not a shark, but chimaera, or relatives who split from the evolutionary cousin sharks approximately 300 million years ago.
These water crature is only known to live near New Zealand and Australia. However, the marine biologists say that this video footage could show a greater range of locations than they previously realized.

"Usually, people probably would not have seen them around this area, so it is a little bit lucky this discovery," said Program Director for Pacific Shark Research Center at Moss Landing Marine Laboratories Dave Ebert, as quoted from National Geographic on Monday, December 19, 2016.
Researchers did not set out to find Hydrolagus Trolli or pointy-nosed blue chimaera when they sent a remotely operated underwater vehicle to explore the waters off of California and Hawaii in 2009. Instead, the scientists involved in this project is a geologist but they studied motherlode marine biology also.
Chimaera which is also known as baronang, ratfish, ghost sharks or chimaeras were prefer cold water from the deep sea. Physically, chimaeras have a bit of their sea dinosaur-like ancestors with scary stripes along the head and body.
