Annelids: Powerful and Capable Worms

The Shape of Life

Annelids have segmented bodies, with both a nervous and circulatory system and a oneway gut. They have mastered the art of digging and live in an incredible diversity of habitats. Tubedwelling worms live in mud flats, stabilizing the mud. Some eat the mud while others collect food from the surface with their tentacles. Blood sucking leeches live in fresh water. Digging in the soil, earthworms both aerate and release nutrients into the soil. See more at: http://shapeoflife.org/video/phyla/an...
