Ghost fish, also known as ghost sharks, belong to the subclass Holocephalis and are called chimaeras. They are aquatic creatures named after combining the characteristics of various animals. Chimaas are still known as "living fossils".

Chimaeras are silvery gray or dark brown and are mainly distributed in the tropical and temperate deeper sea areas of the Atlantic and Pacific Oceans. They usually live on the bottom of the deep sea. The marine life is a distant relative of modern sharks, which existed about 4 years ago. Billions of years ago, ghost sharks split off from their closest relatives, the shark family.

The ghost shark is black and purple in color and has a very strange appearance. It is darker and weirder than all known sharks. In order to find prey in the dark deep sea, the ghost shark has evolved sensitive receptors on its head. There are organs on the body and face that are responsible for capturing changes in the electric fields of other animals for preying.

The chimaera is a cartilaginous fish derived from the ancestor of the shark. It is also known as a living fossil. It has no bones and is composed of cartilage. The ghost shark was previously only found in Australia, New Zealand, and New Caledon in the southern hemisphere. Appeared in the waters near Nia.

The process by which ghost sharks were discovered:

Researchers from the Monterey Aquarium Research Institute in the United States conducted experiments in Southern California and California in 2009. The pointed-nosed blue chimaera has been photographed many times in the waters of central China and the Hawaiian Islands. This underwater creature also has a very domineering name - ghost shark.

In October 2009, the agency released a research report and related videos on this species. It is understood that the Monterey Bay Aquarium Research Institute is not deliberately looking for this creature, it is just A happy accident.

"International Geography" once introduced that the ghost shark is a species older than dinosaurs. Its shape is the same as the underwater creatures described in many science fiction novels-lifeless eyes, blue Gray, sexual organs grow on the forehead and can also be retracted.

This sharp-nosed blue chimaera has never been photographed alive before, and at first, scientists had no idea they could live in the Northern Hemisphere.
