Tube Worms
The tube worm's most noticeable characteristic is its size. These are not like any worms found on land and can grow more than six meters long. Tube worms are found in the Pacific Ocean's depths. They are generally located around hydrothermal vents on the ocean's bed, usually several miles below the surface. Tube worms are a very distinctive red color. This is caused by the excessive amounts of hemoglobins. This type of worm has muscles which help to move around and wiggle. They cannot hold themselves up, they just crawl.
