Title: How are annelid worms, such as earthworms, different from other worms? Post by: torivega11 on Aug 5, 2013 Their bodies are divided into segments.
They have a digestive system. They live inside the bodies of other animals. Their bodies have bilaterial symmetry. Title: How are annelid worms, such as earthworms, different from other worms? Post by: judgement45 on Aug 5, 2013 Phylum annelida includes classes:
-clitellata - earthworms, leeches -Polychaeta - bristle/marine worms The diagnostic features you have listed are correct. A few others are: -Many have chaetae/setae (not leeches) for movement -Peristaltic movement -some have cutting jaws for cutting tissue -Clitellata = Hermaphrodites -Polychaeta = external fertilisation (release of eggs and sperm) Title: How are annelid worms, such as earthworms, different from other worms?

The rest of the points can be applied to other worms but annelids are the only ones with segmented bodies. |
