Snakes live everywhere on Earth except in Ireland, Iceland, New Zealand, and the North and South Poles.

    Of the approximately 725 species of venomous snakes worldwide, 250 can kill a human with a bite.

    The heaviest snake in the world is the anaconda. It weighs over 595 pounds (270 kg) and can grow to over 30 feet long. It has been known to eat caimans, capybaras, and jaguars

    The most advanced snake species in the world is believed to be the black mamba. It has the most highly evolved venom delivery system of any snake on Earth. It can strike up to 12 times in a row, though just one bite is enough to kill a grown man

    The inland taipan is the world’s most toxic snake, meaning it has both the most toxic venom and it injects the most venom when it bites. Its venom sacs hold enough poison to kill up to 80 people

    Snakes scales are made up of keratin, which is the same thing that our fingernails are made from

    The biggest snake is the Reticulated Python. It can grow up to 10.05 m or 33 feet long!

    The thread snake is the smallest snake. It is only about 10 cm the size of a toothpick.
