This 17 December 2018 video from Florida in the USA says about itself:
Wild River Otter Encounter
A pair of River Otters frolicking and rolling on the bank of a marsh. It’s mating season now, so these two may be a couple. Most glimpses of otters are as they cross roadways as in the thumbnail and sadly many get killed by cars so it is a delight to see these amazing creatures living safely in their natural environment. Special bird moment for those who watch until the end!
