Footage has shown the lonely lives of two marine animals in a Seaquarium tank as they were seen repeating the same movements all day.

The clip, filmed last month at what is believed to be the Miami Seaquarium park, was uploaded to Reddit where people reacted with sympathy.

It shows Lolita the orca, who was first captured back in 1970, lightly moving around in one corner of her exhibit.

On the other side of the watered enclosure, Li’i the pacific white-sided dolphin - captured in 1988 - can be seen swimming laps repeatedly.

Reddit users were left fuming by the footage, with one person writing: "That's not interesting that's just animal cruelty."

Another commented: "Hell on earth for them. Hopefully some process of nature has numbed their minds until they are finally able to die. Stop giving these people your money."

Fortunately, there is a silver lining in this story.

In March, Seaquarium announced that Lolita would be set free, after 53 years in captivity.

In a statement, they said: "Lolita will receive the highest quality care as the team works to make relocation possible in the next 18 to 24 months."

The tank that Lolita lives in is 80 feet long and 35 feet wide - she hasn't performed for members of the public since last year.
