Here's the story as reported in the Telegraph -
Dean Qiongxiu, 66, said she discovered the reptile clinging to the wall of her bedroom with its talons in the middle of the night...
Mrs Duan said she was so scared she grabbed a shoe and beat the snake to death before preserving its body in a bottle of alcohol...
A more common mutation among snakes is the growth of a second head.. but have very little chance of surviving in the wild anyway, especially as the heads have a tendency to attack each other.
What strikes my eye (apart from the Biblical damage the lady did on the snake's head) is the reptile-sized lump in the middle of the snake's body and the resemblance of the situation to that of the hawk with a songbird's claw protruding from its gullet:
I think last year I blogged a video of a snake that swallowed a frog and then the frog clambored back out of the snake's mouth, which I can't find at the moment (but you could look it up on YouTube...).
Credit for best comment so far goes to Blackstar at Reddit:
What we're looking at here is a lizard so powerful that it bursts through the body of a snake that has eaten it and then proceeds to climb a wall with its sole exposed limb. With a one-armed snake we could at least take solace in the fact that natural selection would probably snuff it out before it passed that adaptation on. A lizard that powerful simply cannot be stopped!Snake photo credit CEN/Europics; story discovered by Arbroath.
Addendum: Found a case of a snake in India with protruding "frog legs" here (no photo).
Second addendum: Pix of (?same) Indian "frog-legged snake" here.
