The animal, dressed in a child’s wetsuit to keep it warm, enjoys floating across the wide pool, before waving at onlookers.
Surya lives at The Institute of Greatly Endangered and Rare Species in Miami, Florida, USA.
He is put in the pool every week to keep him active and challenged and appears to enjoy splashing about with his trainers.
Animal expert Dr Bhagavan Antle said: “Suyra loves playing in the water. But he doesn’t like getting his head wet, so he wears a lifejacket so he doesn’t go underneath.
“He is quite content when he’s bobbing around on the top. And he loves the jet ski because he can look down on all of us.”
