Although a sunken ship is a tragedy and the end of one life, it is also the beginning of new life, researches say. 321 years ago the HMS Sussex , a war vessel from the British Navy, sank. A horrific storm hit and all of its 500 person crew perished. The ship sank 900 meters to the bottom of the ocean in the straight of Gibraltar. tis horrible tragedy turned out to be a good thing for the animals at the bottom of the ocean. The reason for new ecosystems popping up in sunken ships is wood falls. This is when wood becomes edible for different animals that would not be able to eat regular wood. it also offers shelter.
