Answer:
In my life I must bare my bloodline I must share.

With pointed fangs I sit and wait; with piercing force I crunch out fate; grabbing victims, proclaiming might; physically joining with a single bite. What am I?
Six legs two heads two hands one long nose. Yet I use only four legs Wherever I go.
I look at you, you look at me. I raise my right, you raise your left. What am I?
It flows out of the soil, It burns you if it boils, And holds us in its coils, More valuable than gold, As black as it is old.
