Sponges protect themselves with spikes in their body.
sponges are use in washing plates,glass of water.some sponges are in/on salted water on the ocean floor.
Sponges displace the ocean's water, and the water that they do "suck up" becomes part of their volume, and thus has no effect on the depth of the oceans. When you remove sponges, they will no longer displace water in the ocean, so the ocean will actually be shallower.
sponges are naturally grown in the ocean floor and then harvested and dried to be used.
