A woman in Texas, America has stumbled across a strange double-headed creature, and the internet is going crazy.

The strange double-headed creature (pictured) seem to blink with one eye. Luján Eroles who found it in her courtyard in Argentina said she thought it was a ‘mutant animal’

Many people thought this strange mutant was actually and Elephant Hawk-Moth Caterpillar.

It has two large ‘eye-markings’ behind the head which tricks predators into thinking it’s bigger than it is.

These strange-looking creatures can be found in a range of habitats including open countryside, woodlands and city gardens.

They grow to more than three inches (8.5cm) long and gets its name because the caterpillars resemble elephant trunks.

‘I had never seen anything like it, it was just like a snake and its eyes were so strange’, said Ms Eroles, adding that the creature seemed to blink with one eye.

‘I looked down and I encountered the strange animal, fear struck me knowing that it could have been poisonous’, she said.

‘We all thought it was a mutant animal, which is why we filmed it and put it online for people to give us their opinions.’

Ms Eroles posted the picture on her Facebook page to ask if anyone knew what it was.

‘I think its a deformed creature. This planet is sooo old that it gives everything a chance to reconstruct into something else’, wrote Robert Moore.

‘One thing for sure it’s not a caterpillar because it has no legs’, he said.

‘This may be the head of a viper’, commented another Facebook user, Fernando Garcia.

‘A disabled snake. He better not go into the woods’, said Cheryl Bagley, who was among the 3,000 people who commented on Ms Eroles’ post.

Many have suggested that the creature is an Elephant Hawk-Moth Caterpillar, known for their horn-like curved spines.

The rough skinned creature looked like a serpent with two heads, measured about four inches (10cm) and had skin just like a snake, according to Ms Eroles

‘We did an extensive Google search on the subject and also several people told us that it was a caterpillar which will become a butterfly’, said Ms Eroles.

‘The reason it was in my courtyard was because it was feeding off vines near my house, and it was camouflaged to look like a form of viper to scare off predators.’
