Start with the front of down. Then, look to the middle: son. Finally, think of the back when I’m going. Fix it together, now show me your worth, What’s the reverse of the creator of earth?

I’m heard in warning, loud and clear, When someone dares to venture near. I wrap the trunks in forest deep, And crossed the seas where waves would leap.

I'm a path of a constant curve. Distance is the thing I preserve. I'm unnoticed lest you observe.

I wear a shell but am no snail, and boast two claws that pinch and flail. I live beneath the ocean's foam, and turn bright red when brought to home. What am I?

Freckled black but dressed in red, I roam around in your green bed. Things that cause brown are what keeps me fed.
