How does the black snake sound when play around?

When a snake hisses, it is trying to say to animals that might threaten it: "leave me alone!"

At the same time, the snake needs to know what sort of animal it is dealing with, and a snake's tongue is an important way for it to find out what is going on around it.

Although it might seem weird to you and me, snakes actually smell with their tongues! So, as you can see, it's very important for a snake to be able to keep poking its tongue out (so it can keep smelling what's around it), at the same time as hissing (to warn animals not to come too close).

Like you and me, a snake needs to keep breathing air to stay alive. Now, you might think that a snake's tongue would get in the way of all that breathing, but, luckily for the snake, it doesn't.

You see, while snakes do most of their smelling with their tongues, they do most of their breathing through their noses. Well, that's true when they're breathing normally, but it's a little bit different when they're huffing and puffing and trying to scare other animals.

Unlike humans, birds, and many other animals, snakes aren't able to make many different sounds - hissing is about as close as a snake will ever get to speaking or singing. Like speaking and singing, though, the sound of a hiss comes from air passing in or out through the snake's mouth, as well as its nose; a hiss is the sound of a snake breathing in or out really heavily.

We humans are lucky - we can make a lot of different noises, and even imitate the sound of a snake hissing. The way we make that noise is different to the way a snake does it though - we put our tongue behind our teeth when we hiss, but for a snake the tongue isn't involved in making sounds at all.

Snakes can't make a lot of different shapes with their mouths, which is part of why they can't make a lot of different sounds.

it will sound like hissing because the snake is happy
