An adorable video has been captured the moment a seal frolics in a river.

The footage was shot by John Hart at Pegwell Bay, between Sandwich and Ramsgate, on Friday.

It shows the sea animal plunging in and out of the water six times, with each dive getting bigger.

Near the end of the 30-second clip, the seal does a huge upward dive with its full body coming out of the water before heading back in, nose first.

Mr Hart shared the footage on social media, saying it looked like the seal was having a “lovely time swimming up river”.

Several Sandwich residents described the footage as “beautiful”, while others said it was “wonderful” to watch.

A large heard of seals currently live in Pegwell Bay.

In the summer, a multi-agency operation was launched to stop people using jet skis in the area, which were disturbing the wildlife.

Police led the initiative in August in a bid to safeguard the animals and anyone found riding the vehicles in a manner which posed a risk to the seals was liable to a fine.

The initiative was set up after Kent Wildlife Trust previously described the jet ski riders’ actions as “anti-social behaviour”, which could create potential dangers for young seals.

Experts said the riders’ actions could scare mothers into abandoning their babies, or cause the seals injury.
