The annelids are called segmented worms
because of the elongated bodies that are divided in a number of
segments. Primitive species consist mainly of identical
segments while others have a set of more specialized segments. The 15000
different segmented worms come in a huge variety of shapes and
colors.
Many of the worms live their lives buried in the sand
while others stand up like flowers. Some are microscopic in size, while
others can reach a length of 3 meters.
The by far largest marine class is the Polychaeta -
the bristle worms.
