Where are tube worms found?
Tubeworms live around hydrothermal vents along the Mid-Ocean Ridge in the Eastern Pacific Ocean. They can grow up to two meters long and ten centimeters in diameter. Tubeworms never leave their tubes, which are made of a hard material called chitin.
Are giant tube worms living organisms?
They exist both as free-living organisms and in a symbiotic relationship within the cells or body of other organisms, such as the tube worm Riftia pachyptila (Figure 1).
How do tube worms grow?
Towering colonies of giant tubeworms (Riftia pachyptila) grow where hot, mineral-laden water flows out of the deep seafloor. Unlike most animals, they don’t eat; instead, bacteria living in their guts transform sulfur into energy for them.
What eats a tube worm?
The vent ecosystem’s top predators are species such as octopus and Zoarcids, two-foot long fish that eat everything from tubeworms to crabs. Just like on land, when an animal dies at a hydrothermal vent, its body is eaten by scavengers or decomposed by bacteria.
Why are tube worms red?
The tubeworms’ feather-like red plumes act as gills, absorbing oxygen from seawater and hydrogen sulfide from vent fluids. This feat is accomplished by a special type of hemoglobin in their blood that can transport oxygen and sulfide at the same time (human hemoglobin transports only oxygen).
What is a giant sea worm?
The giant tube worm, also known as Riftia pachyptila, was totally unknown to science until researchers exploring the deep Pacific Ocean floor discovered strange, hydrothermal vents. These giant tube worms grow up to eight feet (over two meters) in length and have no mouth and no digestive tract.
Are spaghetti worms harmful to humans?
