Bottlenose dolphins Yaiza and Gara used to swim hundreds of miles a day off the coast of Cuba - frequently diving to depths of 55 metres in the Caribbean Sea.
But for the last 27 years the pair have been imprisoned in a concrete, barren tank where they are forced to perform daily for holidaymakers - part of a multi-million-pound industry - after they were captured from the wild.
The last captive dolphin attraction in the UK closed in 2003 ending the cruelty of keeping such intelligent creatures in confinement but there are still more than 3,000 in held tourist entertainment venues around the world.
