I am liquid on something solid, i'm tortuous and i can finish in two ways. I born in the montain and i die in the sea What am I?

You and I are always together, Though you'll only see me in fair weather. I can take any shape, long or round, Yet I can never rise from the ground. What am I?

I gather without hands, Scratch the earth but never bleed, I leave long scars that heal at once Pulling things together, tidy up into lumps

I have venomous spurs but I’m not a snake, a weird creature with parts that seem fake. In rivers I dwell with a tail like a beaver, protecting my eggs, a mammalian mother. What am I?

I told you my name was a lie, But in fact that too was untrue, For spirits can dance, And you might chance a glance, In the night, if the lights prance for you
