Dolphins used for these encounters are often violently torn away from their families and ocean homes.
Kimberley Walsh has been slated after she shared photos of her and her family swimming with dolphins.
The mum-of-three was on holiday with her husband and three sons in Dubai.
The singer's followers were horrified when she posted the photos from her family holiday.
One wrote, "Do you know they drug the dolphins?"
"This really isn’t something you should be promoting. I really hope all these shocked comments will be a wake up call to educate yourself."
"I can’t believe you actually paid to have this photo taken with this wonderful animal you are paying to keep it captive instead of out in the sea where it belongs. You are justifying its suffering," one of Kimberley's followers wrote.
"Dolphins belong in the ocean, not fish tanks where humans can profit off their suffering," another said.
Peta called out the singer for such reckless behaviour.
They told Metro, "For crying out loud – hasn’t Kimberley seen The Cove? If she had, she’d understand that dolphins used for these encounters are often violently torn away from their families and ocean homes."
Peta continued, "Instead of exploring, raising their young, and swimming vast distances, dolphins in captivity are forced to spend decades performing confusing tricks in cramped tanks while being fondled by strangers."
"Peta has contacted Kimberley with this information, which we hope will open her eyes to the plight of captive dolphins and will encourage her never ever to support industries that imprison wild animals for profit," Peta added.
