Juxtaposition of Life and Death

1. A missile that swam, now lying in front of me dead.

2. Dead in front of me, catafalqued king of my own ocean. Once sappy as a sprung fir in the green turmoil, 

3. Once seed to sea-quake, tidal wave, now simply dead remains.

4. The only true machine of the sea: unflawed, undefiled, navigating now the waters of death.

The poem uses a lot of juxtaposition between motion and death.
