Here are some interesting facts about snakes:

Movement: Snakes have five ways of moving: sidewinding, concertina movement, lateral undulation, rectilinear locomotion, and slide-pushing. 

Senses: Snakes smell with their tongues, which they flick to pick up chemical particles. 

Eyes: Snakes don't have eyelids, but instead have a thin membrane called a brille that protects their eyes. 

Reproduction: Not all snakes lay eggs, some give birth to live young. 

Speed: Snakes can strike faster than the blink of an eye, accelerating at more than 20 Gs. 

Venom: Some of the most venomous snakes in the world live in the sea. 

Habitat: Snakes live almost everywhere on Earth, except for Greenland, Iceland, Ireland, and New Zealand. 

Behavior: Snakes are mostly solitary, except during mating season. They are not aggressive or territorial, and only strike when threatened or to eat. 

Tongue: Snakes use their tongues to smell their environment. When a snake flicks its tongue, it picks up chemical particles. 

Sea snakes: All sea snakes are venomous and highly toxic.
