Inside eerie 'alien-like' eggs that contain the most venomous snakes in the world

Eerie new images have revealed what the inside of eggs containing the most venomous animals in the world look like.

The eggs shows veins and a dark mass seen through the shell, resembling an alien-like form.

The cluster of eastern brown snake eggs was "gifted" to a snake catcher in New South Wales, Australia, say reports.

Sean Cade, the owner of Australians Snake Catchers, became a surrogate mum to 23 "perfect eggs" last month after a snake laid them in his bag overnight.

He says this event was "rare" and that they will hatch "sometime in March".

Sean has also joked that his friend is currently acting as a stand-in aunty.

Speaking to 9news.com.au, Sean said: "She has got the incubator.

"She's misting them. Snake eggs are leathery and soft, not rock hard like a bird egg, so they need moisture".

He added that once the brown snakes lay their eggs in the wild they leave them, adding that 16 is the average number laid.

Sean says that out of the 23 eggs laid, only about six looks like they are going to hatch.

He added: "Six is good, if I can save one of these eggs that's a good result in my book."

He says when the snakes are born they will have to be returned to the wild because they will be just as venomous as their adult counterparts.

Eastern brown snakes are considered Australia's second most venomous land snake.

They can grow to be about seven feet in length and are found in Australia and southern New Guinea.

Eastern brown snakes prey of choice are mice.

These deadly snakes are responsible for about 60 per cent of human snake-bite deaths in Australia.

When they bite, its venom attacks the circulatory system and can cause haemorrhage, cardiovascular collapse and cardiac arrest.

Last year, a pet cat died after fighting off an eastern brown snake to protect its owner's young children.

Shorthair cat Arthur was playing in the garden with the kids at the family's home in Queensland, Australia, when the eastern brown snake slithered over.

Animal Emergency Service said in a Facebook post the pet quickly pounced, killing the reptile before it could strike.

However, the snake - which carries the second most toxic venom in the world - managed to bite Arthur during the struggle.
