Four new “Bjorn” skate rays have been named after the members of Abba as the city celebrates the 50th anniversary of the group’s Eurovision win in Brighton.

Sea Life Brighton has aptly named the four new baby rays Bjorn, Benny, Agnetha and Frida in tribute to the Swedish group who shot to fame after their Waterloo performance at the Dome won Eurovision 1974.

The rays are the first to be born at the aquarium, which is the oldest in the world, in more than eight years.

Several species of skate exist in UK waters and are all considered to be either threatened or endangered.

Baby rays measure as small as 12cm, which is tiny compared to their 120cm parents, and are born inside an egg case, which is also known as a mermaid purse.

Once hatched they are vulnerable to predation, destructive fishing practices, starvation and pollution.

Sea Life Brighton has recently installed a new exhibition, the Brighton Elasmobranch Nursery, to support its native shark and ray conservation work.

The display depicts the Sussex chalk cliff coastline and features a vast array of local species for visitors to learn about.

Joe Williams, curator of Sea Life Brighton, said "We are over the moon to see our ‘Super Trouper’ thornback skate eggs hatching successfully. A great deal of care and attention has gone into creating our nursery at Sea Life Brighton, which showcases the wonders of our Sussex shores.

“Whilst naming our new ‘Bjorn’ rays after the legends that are Abba seems only fitting on the 50th anniversary of their big win in Brighton, the new habitat will play a key role in helping us to educate our guests about both the human and natural threats our shores are currently facing and help us to educate them on what they can do to make a difference to the local waters and the animals that live along our shorelines.”
