Angel sharks, one of the world’s “rarest” sharks, have been discovered by fishermen off the coast of Wales — a promising sign of life for the critically* endangered* animal.
The flat-bodied sharks, which typically swim along the ocean floor, were most recently spotted in Cardigan Bay off the Welsh coast, in the Bristol Channel (between England and Wales) and near Holyhead, north Wales.
With the population of the angel shark continuing to decline* quickly, researchers decided to investigate the fishermen’s sighting.
The Zoological Society of London (ZSL) and Natural Resources Wales launched the Angel Shark Project: Wales last year in an attempt to raise awareness around the species’ dwindling* numbers.
The project encouraged people to make contact with any reported sightings of the elusive* sea creature.
Last week, the group asked residents to share photos and memories of the endangered species during its first roadshow.
“Angel sharks are important to the marine environment as they are a top predator* and are listed as the fifth most evolutionarily* distinct* and globally endangered shark in the world,” the ZSL explained on its website.

It also noted that the Welsh coast may be an important home for the species.
Angel sharks used to be fairly common across the Atlantic and Mediterranean seas, but a disrupted habitat*, pollution and overfishing have helped cause their lower numbers.
Scientists hope the recent sightings will help provide clues around the angel shark’s behaviour and preferred habitat and help save the mysterious sharks from extinction*.
“If we lose the angel shark, we lose a really important lineage of evolutionary history that we can’t get from any other shark species,” marine biologist Joanna Barker told BBC News.
To further study the rare sharks, Ms Barker said researchers will take swabs of the shark’s skin during dives which are scheduled for later this year.
