A popular penguin at Torquay’s coastal zoo is being treated for a suspected heart condition.
Yoyo the macaroni penguin is well known for hanging around the public walkways and greeting guests.
Zoo vet Christa van Wessem says Yoyo was named to reflect his tough start in life.
In October last year Yoyo became unwell and since then staff have taken blood samples and x-rays to find out what was wrong.
Yoyo - who turns five on Sunday - was also given a CT scan at Abbotskerswell Veterinary Centre.
A computerised tomography (CT or CAT scan) uses x-rays to create detailed computer images of the inside of a body.
Specialists found some possible heart issues, including the suspicion of a slightly enlarged heart.
Yoyo is now on the sort of medication a human would take, helping to reduce the strain on his heart partly by reducing his blood pressure.
His keepers give him his daily dose hidden inside a raw fish.
