There are fascinating animals in every corner of the British Isles but many of these can be hard to spot due to their rarity.

Snakes are one of these with many coming to the mistaken conclusion that the UK is free of these slithering creatures.

If you've ever wondered how likely you are to catch a glimpse of a snake, here is everything you need to know.

Snakes are a rare sight in the UK but can be spotted in the wild and/or in gardens during the warmer months.

According to the RSPCA, there are three native species in the UK with these being the Adder, Grass Snake and Smooth Snake.

The Adder, which is widespread has seen a decline in its numbers in recent years.

The Grass Snake is commonly found in gardens across England and Wales and can grow to be over a metre long.

Finally, the Smooth Snake - the rarest of these - is localised to the south of England.

Are there any venomous snakes in the UK?

The previously mentioned Adder is the only venomous snake native to the UK. These snakes are identifiable by the "distinctive zigzag pattern down their back, red eyes and a vertical pupil," according to the RSPCA.

Bites from these animals are generally not life-threatening. However, these can be extremely painful and cause inflammation.

Adder bites are most dangerous for the very young, elderly and those who are ill.

In some rare cases, Adder bites can lead to some extreme outcomes, causing those affected to require hospitalisation.

Fatalities are also rare with only ten being recorded in the last 100 years.
