An army of bright yellow frogs has been filmed croaking and hopping around a flooded field in India.

Males of the 6.9-inch Indian Bullfrog swap their usual greens and browns for the flashy shade between June and July every year, their mating season.

The bizarre footage was taken by an Indian national parks worker as he surveyed the amphibians in Narsinghpur, Madhya Pradesh.

In the video a gaggle of yellow males is seen splashing around the flood waters, with fewer green females in sight.

Several males were also shown inflating their cheeks, revealing a brilliant blue colour, which they use to attract mates.

The video has gone viral and been viewed more than 144,000 times since it was uploaded to the internet.

'They are Indian bullfrogs and they change to yellow during the monsoon for attracting females. 

'Just look how they are enjoying the rains.'  

He also explained to viewers how, despite their colour, the frogs are not poisonous and are actually sometimes eaten by people.

He later added: 'The only issue is whether so many males will get their ladies. 

'The competition is real.'

The Indian Bullfrog, or Hoplobatrachus tigerinus, is a species of least concern according to the IUCN, meaning it is not under threat from human activity.

It can be found in Afghanistan, Bangladesh, India, Myanmar, Nepal, Pakistan and Sri Lanka.

But the population has also spread to other locations - and has managed to invade Madagascar, the Maldives and India's Andaman islands.

The species is famous for having a voracious appetite and eating any thing it can get its tongue around - even small birds, mice and other frogs.

Their tadpoles are also dangerous, and are known to eat the tadpoles of other smaller frog species.

The Indian monsoon lasts between June and July.
