Two dolphins were found dead on the banks of the River Thames in London after one was spotted in the river last week.
The dolphin, which is a type of common dolphin, was seen multiple times on Thursday and appeared to be struggling with the strong tides.
One of the dolphins was found near Chelsea Harbour Pier, while the other was found on the riverbank at Greenwich.
The incident is being investigated by the Port of London Authority, who are working with experts to understand why the dolphins died.
