A small world

Deep in underwater canyons small creatures live and feed off of microscopic debris from the surface. Their are many different types of these mini organisms underwater including; clams, many types of worms, and crustaceans. These creatures have some predators, but are usually in a good healthy numbers. Scientist have taken samples over 2,500 meters deep and have founded only half the number of these organisms that recorded before. The cause of this is larger animals like crabs or urchins, they scrape and move the ground which makes it harder for the mini organisms to live.

I find it amazing that their are many different worlds so close to us. Some creatures are so small you can only see them with a microscope. Creatures like these are important for the animal food chain, without small organisms like plankton or the mini creatures, bigger creatures would die and this would cause a chain reaction.
