Hello I am new and this is my first riddle, sorry for the bad english!
You should guess what am I
I'll tell you Mark is my name
There are many friends of mine
but I'm the easier to tame
I won't talk so much about my head
I'll just let you know that without it I wouldn't be dead
Let's talk about my body
I don't have any legs, arms or horns
but it can have many shapes or forms
I am all over the world
You can find me if you search far and wide
Try to look near the spider's lair
You can see the real me
If you just try hard a bit
What is it?
