While it is true that some snake species lay eggs, that's not true for all snakes. While about 70% of snake species lay eggs, the rest, like boa constrictors and anacondas, deliver their young directly, without eggs.
Curiously, no. Snakes aren't naturally found in Antarctica, the North and South poles, Greenland, Iceland, Ireland and New Zealand.
While this is true for the modern snakes, once upon a time, they had legs. In fact, snakes, such as pythons and boas, still have remnants of back legs.
A popular misinformation is that snakes can't smell. They can, and very well. However, instead of nostrils, they use their tongues to do so.
It is falsely said that snakes are cold-blooded, in fact they fully depend on external heat sources like the sun to warm up.
