I cradle shells upon the shore, and hide strange creatures near my floor. With swaying seaweed and fish that roam, I am their vast and endless home.

Beneath the earth where sunlight dies, with stone for walls and barred confines. No open sky, no freedom near, a place of shadows, dread, and fear.

My first and last letter is a type of cow. My two middle letters is a state in USA. What am I?

In the cold, stormy night my gaze might save your life.

Mars, Antarctica, Mount Everest, or your Great Aunt May who offers turnips and unsweetened lemonade when you visit.
