One of the "sharper" sharks in the world, the angel shark, was discovered by fishermen from the coast of Wales – a promising sign of life for the critically endangered creature.
The shark "body planes", which usually do not fit along the oceans, have recently been reported by Cardigan Bay, the Bristol Channel and near Holyhead. Because the population of the shark of angel continues to decline dramatically, researchers have decided to explore.
Last year, the Zoological Society of London (ZSL) and Natural Resources Wales (NRW) began the "Angel Shark Project: Wales", encouraging people to contact them if they see the sea. On Thursday, the groups asked the residents to share photos and memories of the endangered species during their first "Angelshark History Roadshow".

"Angels sharks are important to the marine environment because they are a prominent predator and are listed as the fifth most Developed Distinction and Worldwide Endangered Shark in the world, representing a distinctive branch of the tree of life," the ZSL explains on its website, noticing the Kimmar coast, can be an important home for the species.
"If we lose the shark shark, we lose a really important line of evolution that we can not get from any other Shark species."
Angels sharks used to be quite common across the Atlantic and Mediterranean seas but interrupted habitat, pollution and superfishing contributed to their death, says ZSL. Scientists expect recent views to help provide clues to the type of behavior and favorite habitat and, in turn, will help save the mystery sharks from removal.
"If we lose the Anglo-Saxon shark, we lose a really important line of evolution that we can not get from any other Shark species," said BBC News, Joanna Barker, a marine biologist who works for the ZSL.
Barker studied sharks for a while, especially around the Canary Islands, but she is now beginning to deepen her history in Welsh waters. With fresh views, she is curious, where the sharks are now called at home and are there different populations.

"What we really try to understand is what numbers we are talking about and where are their important habitats, since there were some really worrying areas for angels in Wales," said Barker.
In order to study the rare sharks, Barker said that researchers would take skeletons of their skin during the apples planned for earlier this year.
Until then, marine experts are hoping to gain even more information on local sharks' sharks – using their photos and stories to help track the movements of the species of the coast of Wales.
