Olivia's dad, David said: "We couldn't believe it when Olivia came home and showed us the video.

"I have never seen an otter around here before ever but I will be looking out for them in future as I think there must be more around.”

Otters, which are often elusive and nocturnal, returned to Lancashire a decade ago after clawing their way back from extinction, according to experts.

Pollution to local waterways had seen them more or less disappear, but the Environment Agency said that as rivers had started to flourish again after serious pollution incidents had been slashed by half since 2001, many animals had returned.

Last year the Ribble Rivers Trust carried out a conservation task to search for signs of otters at several local sites.

The survey was launched to discover if otter numbers were on the rise on the River Ribble which flows through Lancashire into Yorkshire.

The Trust said that Eurasian otters are ‘near threatened’ with extinction, with their population having crashed in the UK in the last century due to pollution, habitat loss and hunting.

But signs were appearing that their numbers were back on the rise but conservationists have no idea how many there are in the area.
