This footage appears to show a dolphin swimming in the River Mersey.
Chris Hemmings took the video on Wednesday and said he was shocked at what he saw.
A lot of people have been reporting cleaner and less polluted areas on Merseyside, such as parks rivers and beaches due to a reduction in human activity.
Chris said he had seen some posts on social media showing the cleaner areas so decided to film what he saw.
Chris said: “A little shocked because I had seen other things on social media mentioning that some wildlife miracles had happened due to less pollution with Corona lock down”
However, the dolphin that was spotted is actually a harbour porpoise that are common to the water in the River Mersey.
